Struct qt_gui::QRasterWindow

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

QRasterWindow is a convenience class for using QPainter on a QWindow

C++ class: QRasterWindow.

C++ documentation:

QRasterWindow is a convenience class for using QPainter on a QWindow

QRasterWindow is a QWindow with a raster-based, non-OpenGL surface. On top of the functionality offered by QWindow, QRasterWindow adds a virtual paintEvent() function and the possibility to open a QPainter on itself. The underlying paint engine will be the raster one, meaning that all drawing will happen on the CPU. For performing accelerated, OpenGL-based drawing, use QOpenGLWindow instead.

Internally the class is thin wrapper for QWindow and QBackingStore and is very similar to the Raster Window Example that uses these classes directly.

Methods

Methods from Deref<Target = QPaintDeviceWindow>

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

Marks the entire window as dirty and schedules a repaint.

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

C++ documentation:

Marks the entire window as dirty and schedules a repaint.

Note: Subsequent calls to this function before the next paint event will get ignored.

Note: For non-exposed windows the update is deferred until the window becomes exposed again.

pub unsafe fn meta_object(&self) -> Ptr<QMetaObject>

Calls C++ function: virtual const QMetaObject* QPaintDeviceWindow::metaObject() const.

pub unsafe fn qt_metacall(
    &self,

) -> c_int

Calls C++ function: virtual int QPaintDeviceWindow::qt_metacall(QMetaObject::Call arg1, int arg2, void** arg3).

pub unsafe fn qt_metacast(&self, arg1: *const c_char) -> *mut c_void

Calls C++ function: virtual void* QPaintDeviceWindow::qt_metacast(const char* arg1).

pub unsafe fn update_q_rect(&self, rect: impl CastInto<Ref<QRect>>)

Marks the rect of the window as dirty and schedules a repaint.

Calls C++ function: void QPaintDeviceWindow::update(const QRect& rect).

C++ documentation:

Marks the rect of the window as dirty and schedules a repaint.

Note: Subsequent calls to this function before the next paint event will get ignored, but rect is added to the region to update.

Note: For non-exposed windows the update is deferred until the window becomes exposed again.

pub unsafe fn update_q_region(&self, region: impl CastInto<Ref<QRegion>>)

Marks the region of the window as dirty and schedules a repaint.

Calls C++ function: void QPaintDeviceWindow::update(const QRegion& region).

C++ documentation:

Marks the region of the window as dirty and schedules a repaint.

Note: Subsequent calls to this function before the next paint event will get ignored, but region is added to the region to update.

Note: For non-exposed windows the update is deferred until the window becomes exposed again.

pub unsafe fn update(&self)

Marks the entire window as dirty and schedules a repaint.

Calls C++ function: [slot] void QPaintDeviceWindow::update().

C++ documentation:

Marks the entire window as dirty and schedules a repaint.

Note: Subsequent calls to this function before the next paint event will get ignored.

Note: For non-exposed windows the update is deferred until the window becomes exposed again.
