Events data sent by the controls.

Variants

NoData

The event has no data

OnWindowClose(WindowCloseData)

Sets if the window should be closed after the event

OnMinMaxInfo(MinMaxInfo)

Contains the default maximized position and dimensions, and the default minimum and maximum tracking sizes. An application can override the defaults by setting the members of this event.

OnTooltipText(ToolTipTextData)

Sets the text of a tooltip. The method on_tooltip_text should be used to access the inner data

OnChar(char)

The character entered by a user by an OnChar event

OnKey(u32)

The windows key code entered by a user. See the nwg::keys module

OnPaint(PaintData)

Hold resources that will most likely be used during painting.

OnMouseWheel(i32)

The delta value of a mouse wheel event. A positive value indicates that the wheel was rotated to the right; a negative value indicates that the wheel was rotated to the left.

OnFileDrop(DropFiles)

The path to one or more files that were dropped in the application

OnTreeItemDelete(TreeItem)

The handle to the item being deleted. The item is still valid.

OnTreeItemUpdate

The handle to the item being changed.

Fields

item: TreeItem

action: TreeItemAction

OnTreeViewEndItemEdit

When ends the editing of a treeview item’s label.

Fields

f_cancel: bool

new_text: String

OnTreeItemSelectionChanged

The handles the the old item and the new item.

Fields

old: TreeItem

new: TreeItem

OnListViewItemIndex

Row index and column index of the list view item that raised the event row_index 0xFFF... means the absence of an item

Fields

row_index: usize

column_index: usize

OnListViewItemChanged

Row index, column index, and selected state of the list view item that raised the event

Fields

row_index: usize

column_index: usize

selected: bool

Implementations

impl EventData

pub fn on_paint(&self) -> &PaintData

Unwraps event data into a &PaintData. Panics if it’s not the right type.

pub fn on_min_max(&self) -> &MinMaxInfo

Unwraps event data into a &MinMaxInfo. Panics if it’s not the right type.

pub fn on_char(&self) -> char

Unwraps event data into a char. Panics if it’s not the right type.

pub fn on_tooltip_text(&self) -> &ToolTipTextData

Unwraps event data into a &ToolTipTextData. Panics if it’s not the right type.

pub fn on_file_drop(&self) -> &DropFiles

Unwraps event data into a &DragData. Panics if it’s not the right type.

pub fn on_key(&self) -> u32

Unwraps event data into the virtual key code for OnKeyPress and OnKeyRelease

pub fn on_tree_item_delete(&self) -> &TreeItem

unwraps event data into the removed tree item

pub fn on_tree_item_update(&self) -> (&TreeItem, TreeItemAction)

unwraps event data into the update tree view item and the action

pub fn on_tree_item_selection_changed(&self) -> (&TreeItem, &TreeItem)

unwraps event data into the removed tree item

pub fn on_tree_view_end_item_edit(&self) -> (bool, String)

unwraps event data into f_cancel, new_text. f_cancel indicates the editing is cancel or not. new_text is the new input text when editing is not cancel.

pub fn on_list_view_item_index(&self) -> (usize, usize)

unwraps event data into the indices of a list view index (row_index, column_index)

pub fn on_list_view_item_changed(&self) -> (usize, usize, bool)

unwraps event data into the indices of a list view index (row_index, column_index, selected)

Trait Implementations

impl Debug for EventData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
