Struct qt_widgets::QStyleOptionTitleBar

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

The QStyleOptionTitleBar class is used to describe the parameters for drawing a title bar.

C++ class: QStyleOptionTitleBar.

C++ documentation:

The QStyleOptionTitleBar class is used to describe the parameters for drawing a title bar.

QStyleOptionTitleBar contains all the information that QStyle functions need to draw the title bar of a QMdiSubWindow.

For performance reasons, the access to the member variables is direct (i.e., using the . or -> operator). This low-level feel makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.

For an example demonstrating how style options can be used, see the Styles example.

Methods

impl QStyleOptionTitleBar

pub unsafe fn icon(&self) -> Ref<QIcon>

Returns a reference to the icon field.

pub unsafe fn icon_mut(&mut self) -> MutRef<QIcon>

Returns a mutable reference to the icon field.

pub unsafe fn new() -> CppBox<QStyleOptionTitleBar>

Constructs a QStyleOptionTitleBar, initializing the members variables to their default values.

Calls C++ function: [constructor] void QStyleOptionTitleBar::QStyleOptionTitleBar().

C++ documentation:

Constructs a QStyleOptionTitleBar, initializing the members variables to their default values.

pub unsafe fn new_copy(
    other: impl CastInto<Ref<QStyleOptionTitleBar>>
) -> CppBox<QStyleOptionTitleBar>

Constructs a copy of the other style option.

Calls C++ function: [constructor] void QStyleOptionTitleBar::QStyleOptionTitleBar(const QStyleOptionTitleBar& other).

C++ documentation:

Constructs a copy of the other style option.

pub unsafe fn set_icon(&mut self, value: impl CastInto<Ref<QIcon>>)

Sets the value of the icon field.

pub unsafe fn set_text(&mut self, value: impl CastInto<Ref<QString>>)

Sets the value of the text field.

pub unsafe fn set_title_bar_flags(&mut self, value: QFlags<WindowType>)

Sets the value of the titleBarFlags field.

pub unsafe fn set_title_bar_state(&mut self, value: c_int)

Sets the value of the titleBarState field.

pub unsafe fn text(&self) -> Ref<QString>

Returns a reference to the text field.

pub unsafe fn text_mut(&mut self) -> MutRef<QString>

Returns a mutable reference to the text field.

pub unsafe fn title_bar_flags(&self) -> QFlags<WindowType>

Returns a reference to the titleBarFlags field.

pub unsafe fn title_bar_state(&self) -> c_int

Methods from Deref<Target = QStyleOptionComplex>

pub unsafe fn active_sub_controls(&self) -> QFlags<SubControl>

Returns a reference to the activeSubControls field.

pub unsafe fn copy_from(
    &mut self,
    other: impl CastInto<Ref<QStyleOptionComplex>>
) -> MutRef<QStyleOptionComplex>

The QStyleOptionComplex class is used to hold parameters that are common to all complex controls.

Calls C++ function: QStyleOptionComplex& QStyleOptionComplex::operator=(const QStyleOptionComplex& other).

C++ documentation:

The QStyleOptionComplex class is used to hold parameters that are common to all complex controls.

This class is not used on its own. Instead it is used to derive other complex control options, for example QStyleOptionSlider and QStyleOptionSpinBox.

For performance reasons, the access to the member variables is direct (i.e., using the . or -> operator).

For an example demonstrating how style options can be used, see the Styles example.

pub unsafe fn set_active_sub_controls(&mut self, value: QFlags<SubControl>)

Sets the value of the activeSubControls field.

pub unsafe fn set_sub_controls(&mut self, value: QFlags<SubControl>)

Sets the value of the subControls field.

pub unsafe fn sub_controls(&self) -> QFlags<SubControl>

Returns a reference to the subControls field.
