Struct qt_core::QConcatenateTablesProxyModel

#[repr(C)]pub struct QConcatenateTablesProxyModel { /* fields omitted */ }

QConcatenateTablesProxyModel takes multiple source models and concatenates their rows.

C++ class: QConcatenateTablesProxyModel.

C++ documentation:

QConcatenateTablesProxyModel takes multiple source models and concatenates their rows.

In other words, the proxy will have all rows of the first source model, followed by all rows of the second source model, and so on.

If the source models don't have the same number of columns, the proxy will only have as many columns as the source model with the smallest number of columns. Additional columns in other source models will simply be ignored.

Source models can be added and removed at runtime, and the column count is adjusted accordingly.

This proxy does not inherit from QAbstractProxyModel because it uses multiple source models, rather than a single one.

Only flat models (lists and tables) are supported, tree models are not.

pub fn rows_about_to_be_moved(
    &self
) -> Signal<(*const QModelIndex, c_int, c_int, *const QModelIndex, c_int)>

This signal is emitted just before rows are moved within the model. The items that will be moved are those between sourceStart and sourceEnd inclusive, under the given sourceParent item. They will be moved to destinationParent starting at the row destinationRow.

Returns a built-in Qt signal QAbstractItemModel::rowsAboutToBeMoved that can be passed to qt_core::Signal::connect.

C++ documentation:

This signal is emitted just before rows are moved within the model. The items that will be moved are those between sourceStart and sourceEnd inclusive, under the given sourceParent item. They will be moved to destinationParent starting at the row destinationRow.

Note: Components connected to this signal use it to adapt to changes in the model's dimensions. It can only be emitted by the QAbstractItemModel implementation, and cannot be explicitly emitted in subclass code.

This function was introduced in Qt 4.6.

Note: This is a private signal. It can be used in signal connections but cannot be emitted by the user.

pub fn slot_reset_internal_data(&self) -> Receiver<()>

This slot is called just after the internal data of a model is cleared while it is being reset.

Returns a built-in Qt slot QAbstractItemModel::resetInternalData that can be passed to qt_core::Signal::connect.

C++ documentation:

This slot is called just after the internal data of a model is cleared while it is being reset.

This slot is provided the convenience of subclasses of concrete proxy models, such as subclasses of QSortFilterProxyModel which maintain extra data.

class CustomDataProxy : public QSortFilterProxyModel
{
      Q_OBJECT
public:
      CustomDataProxy(QObject *parent)

pub fn data_changed(
    &self
) -> Signal<(*const QModelIndex, *const QModelIndex, *const QVectorOfInt)>

This signal is emitted whenever the data in an existing item changes.

Returns a built-in Qt signal QAbstractItemModel::dataChanged that can be passed to qt_core::Signal::connect.

C++ documentation:

This signal is emitted whenever the data in an existing item changes.

If the items are of the same parent, the affected ones are those between topLeft and bottomRight inclusive. If the items do not have the same parent, the behavior is undefined.

When reimplementing the setData() function, this signal must be emitted explicitly.

The optional roles argument can be used to specify which data roles have actually been modified. An empty vector in the roles argument means that all roles should be considered modified. The order of elements in the roles argument does not have any relevance.

See also headerDataChanged(), setData(), and layoutChanged().

pub fn layout_changed(
    &self
) -> Signal<(*const QListOfQPersistentModelIndex, LayoutChangeHint)>

This signal is emitted whenever the layout of items exposed by the model has changed; for example, when the model has been sorted. When this signal is received by a view, it should update the layout of items to reflect this change.

Returns a built-in Qt signal QAbstractItemModel::layoutChanged that can be passed to qt_core::Signal::connect.

C++ documentation:

This signal is emitted whenever the layout of items exposed by the model has changed; for example, when the model has been sorted. When this signal is received by a view, it should update the layout of items to reflect this change.

When subclassing QAbstractItemModel or QAbstractProxyModel, ensure that you emit layoutAboutToBeChanged() before changing the order of items or altering the structure of the data you expose to views, and emit layoutChanged() after changing the layout.

The optional parents parameter is used to give a more specific notification about what parts of the layout of the model are changing. An empty list indicates a change to the layout of the entire model. The order of elements in the parents list is not significant. The optional hint parameter is used to give a hint about what is happening while the model is relayouting.

Subclasses should update any persistent model indexes before emitting layoutChanged(). In other words, when the structure changes:

• emit layoutAboutToBeChanged
• Remember the QModelIndex that will change
• Update your internal data
• Call changePersistentIndex()
• emit layoutChanged

This function was introduced in Qt 5.0.

See also layoutAboutToBeChanged(), dataChanged(), headerDataChanged(), modelReset(), and changePersistentIndex().

pub fn layout_about_to_be_changed(
    &self
) -> Signal<(*const QListOfQPersistentModelIndex, LayoutChangeHint)>

This signal is emitted just before the layout of a model is changed. Components connected to this signal use it to adapt to changes in the model's layout.

Returns a built-in Qt signal QAbstractItemModel::layoutAboutToBeChanged that can be passed to qt_core::Signal::connect.

C++ documentation:

This signal is emitted just before the layout of a model is changed. Components connected to this signal use it to adapt to changes in the model's layout.

pub unsafe fn buddy(
    &self,
    index: impl CastInto<Ref<QModelIndex>>
) -> CppBox<QModelIndex>

Returns a model index for the buddy of the item represented by index. When the user wants to edit an item, the view will call this function to check whether another item in the model should be edited instead. Then, the view will construct a delegate using the model index returned by the buddy item.

Calls C++ function: virtual QModelIndex QAbstractItemModel::buddy(const QModelIndex& index) const.

C++ documentation:

Returns a model index for the buddy of the item represented by index. When the user wants to edit an item, the view will call this function to check whether another item in the model should be edited instead. Then, the view will construct a delegate using the model index returned by the buddy item.

The default implementation of this function has each item as its own buddy.

pub unsafe fn can_drop_mime_data(
    &self,
    data: impl CastInto<Ptr<QMimeData>>,
    action: DropAction,
    row: c_int,
    column: c_int,
    parent: impl CastInto<Ref<QModelIndex>>
) -> bool

Returns true if a model can accept a drop of the data. This default implementation only checks if data has at least one format in the list of mimeTypes() and if action is among the model's supportedDropActions().

Calls C++ function: virtual bool QAbstractItemModel::canDropMimeData(const QMimeData* data, Qt::DropAction action, int row, int column, const QModelIndex& parent) const.

C++ documentation:

Returns true if a model can accept a drop of the data. This default implementation only checks if data has at least one format in the list of mimeTypes() and if action is among the model's supportedDropActions().

Reimplement this function in your custom model, if you want to test whether the data can be dropped at row, column, parent with action. If you don't need that test, it is not necessary to reimplement this function.

See also dropMimeData() and Using drag and drop with item views.

pub unsafe fn can_fetch_more(
    &self,
    parent: impl CastInto<Ref<QModelIndex>>
) -> bool

Returns true if there is more data available for parent; otherwise returns false.

Calls C++ function: virtual bool QAbstractItemModel::canFetchMore(const QModelIndex& parent) const.

C++ documentation:

Returns true if there is more data available for parent; otherwise returns false.

The default implementation always returns false.

If canFetchMore() returns true, the fetchMore() function should be called. This is the behavior of QAbstractItemView, for example.

See also fetchMore().

pub unsafe fn check_index_2a(
    &self,
    index: impl CastInto<Ref<QModelIndex>>,
    options: QFlags<CheckIndexOption>
) -> bool

This is supported on cpp_lib_version="5.11.3" or cpp_lib_version="5.12.2" or cpp_lib_version="5.13.0" or cpp_lib_version="5.14.0" only.

This function checks whether index is a legal model index for this model. A legal model index is either an invalid model index, or a valid model index for which all the following holds:

Calls C++ function: bool QAbstractItemModel::checkIndex(const QModelIndex& index, QFlags<QAbstractItemModel::CheckIndexOption> options = …) const.

C++ documentation:

This function checks whether index is a legal model index for this model. A legal model index is either an invalid model index, or a valid model index for which all the following holds:

• the index' model is this;
• the index' row is greater or equal than zero;
• the index' row is less than the row count for the index' parent;
• the index' column is greater or equal than zero;
• the index' column is less than the column count for the index' parent.

The options argument may change some of these checks. If options contains IndexIsValid, then index must be a valid index; this is useful when reimplementing functions such as data() or setData(), which expect valid indexes.

If options contains DoNotUseParent, then the checks that would call parent() are omitted; this allows calling this function from a parent() reimplementation (otherwise, this would result in endless recursion and a crash).

If options does not contain DoNotUseParent, and it contains ParentIsInvalid, then an additional check is performed: the parent index is checked for not being valid. This is useful when implementing flat models such as lists or tables, where no model index should have a valid parent index.

This function returns true if all the checks succeeded, and false otherwise. This allows to use the function in Q_ASSERT and similar other debugging mechanisms. If some check failed, a warning message will be printed in the qt.core.qabstractitemmodel.checkindex logging category, containing some information that may be useful for debugging the failure.

Note: This function is a debugging helper for implementing your own item models. When developing complex models, as well as when building complicated model hierarchies (e.g. using proxy models), it is useful to call this function in order to catch bugs relative to illegal model indices (as defined above) accidentally passed to some QAbstractItemModel API.

Warning: Note that it's undefined behavior to pass illegal indices to item models, so applications must refrain from doing so, and not rely on any "defensive" programming that item models could employ to handle illegal indexes gracefully.

This function was introduced in Qt 5.11.

See also QModelIndex.

This is supported on cpp_lib_version="5.11.3" or cpp_lib_version="5.12.2" or cpp_lib_version="5.13.0" or cpp_lib_version="5.14.0" only.

This function checks whether index is a legal model index for this model. A legal model index is either an invalid model index, or a valid model index for which all the following holds:

Calls C++ function: bool QAbstractItemModel::checkIndex(const QModelIndex& index) const.

C++ documentation:

pub unsafe fn column_count_1a(
    &self,
    parent: impl CastInto<Ref<QModelIndex>>
) -> c_int

Returns the number of columns for the children of the given parent.

Calls C++ function: pure virtual int QAbstractItemModel::columnCount(const QModelIndex& parent = …) const.

C++ documentation:

Returns the number of columns for the children of the given parent.

In most subclasses, the number of columns is independent of the parent.

For example:

int DomModel::columnCount(const QModelIndex &/parent/) const
{
      return 3;
}

Note: When implementing a table based model, columnCount() should return 0 when the parent is valid.

See also rowCount().

pub unsafe fn column_count_0a(&self) -> c_int

Returns the number of columns for the children of the given parent.

Calls C++ function: pure virtual int QAbstractItemModel::columnCount() const.

C++ documentation:

Returns the number of columns for the children of the given parent.

In most subclasses, the number of columns is independent of the parent.

For example:

int DomModel::columnCount(const QModelIndex &/parent/) const
{
      return 3;
}

Note: When implementing a table based model, columnCount() should return 0 when the parent is valid.

See also rowCount().

pub unsafe fn data_2a(
    &self,
    index: impl CastInto<Ref<QModelIndex>>,
    role: c_int
) -> CppBox<QVariant>

Returns the data stored under the given role for the item referred to by the index.

Calls C++ function: pure virtual QVariant QAbstractItemModel::data(const QModelIndex& index, int role = …) const.

C++ documentation:

Returns the data stored under the given role for the item referred to by the index.

Note: If you do not have a value to return, return an invalid QVariant instead of returning 0.

See also Qt::ItemDataRole, setData(), and headerData().

pub unsafe fn data_1a(
    &self,
    index: impl CastInto<Ref<QModelIndex>>
) -> CppBox<QVariant>

Returns the data stored under the given role for the item referred to by the index.

Calls C++ function: pure virtual QVariant QAbstractItemModel::data(const QModelIndex& index) const.

C++ documentation:

Returns the data stored under the given role for the item referred to by the index.

Note: If you do not have a value to return, return an invalid QVariant instead of returning 0.

pub unsafe fn drop_mime_data(
    &self,
    data: impl CastInto<Ptr<QMimeData>>,
    action: DropAction,
    row: c_int,
    column: c_int,
    parent: impl CastInto<Ref<QModelIndex>>
) -> bool

Handles the data supplied by a drag and drop operation that ended with the given action.

Calls C++ function: virtual bool QAbstractItemModel::dropMimeData(const QMimeData* data, Qt::DropAction action, int row, int column, const QModelIndex& parent).

C++ documentation:

Handles the data supplied by a drag and drop operation that ended with the given action.

Returns true if the data and action were handled by the model; otherwise returns false.

The specified row, column and parent indicate the location of an item in the model where the operation ended. It is the responsibility of the model to complete the action at the correct location.

For instance, a drop action on an item in a QTreeView can result in new items either being inserted as children of the item specified by row, column, and parent, or as siblings of the item.

When row and column are -1 it means that the dropped data should be considered as dropped directly on parent. Usually this will mean appending the data as child items of parent. If row and column are greater than or equal zero, it means that the drop occurred just before the specified row and column in the specified parent.

The mimeTypes() member is called to get the list of acceptable MIME types. This default implementation assumes the default implementation of mimeTypes(), which returns a single default MIME type. If you reimplement mimeTypes() in your custom model to return multiple MIME types, you must reimplement this function to make use of them.

See also supportedDropActions(), canDropMimeData(), and Using drag and drop with item views.

pub unsafe fn fetch_more(&self, parent: impl CastInto<Ref<QModelIndex>>)

Fetches any available data for the items with the parent specified by the parent index.

Calls C++ function: virtual void QAbstractItemModel::fetchMore(const QModelIndex& parent).

C++ documentation:

Fetches any available data for the items with the parent specified by the parent index.

Reimplement this if you are populating your model incrementally.

The default implementation does nothing.

See also canFetchMore().

pub unsafe fn flags(
    &self,
    index: impl CastInto<Ref<QModelIndex>>
) -> QFlags<ItemFlag>

Returns the item flags for the given index.

Calls C++ function: virtual QFlags<Qt::ItemFlag> QAbstractItemModel::flags(const QModelIndex& index) const.

C++ documentation:

Returns the item flags for the given index.

The base class implementation returns a combination of flags that enables the item (ItemIsEnabled) and allows it to be selected (ItemIsSelectable).

See also Qt::ItemFlags.

pub unsafe fn has_children_1a(
    &self,
    parent: impl CastInto<Ref<QModelIndex>>

Calls C++ function: virtual bool QAbstractItemModel::insertRows(int row, int count, const QModelIndex& parent = …).

C++ documentation:

Note: The base class implementation of this function does nothing and returns false.

On models that support this, inserts count rows into the model before the given row. Items in the new row will be children of the item represented by the parent model index.

If row is 0, the rows are prepended to any existing rows in the parent.

If row is rowCount(), the rows are appended to any existing rows in the parent.

Calls C++ function: pure virtual QModelIndex QAbstractItemModel::parent(const QModelIndex& child) const.

C++ documentation:

Returns the parent of the model item with the given index. If the item has no parent, an invalid QModelIndex is returned.

A common convention used in models that expose tree data structures is that only items in the first column have children. For that case, when reimplementing this function in a subclass the column of the returned QModelIndex would be 0.

When reimplementing this function in a subclass, be careful to avoid calling QModelIndex member functions, such as QModelIndex::parent(), since indexes belonging to your model will simply call your implementation, leading to infinite recursion.
