Member Function Documentation

◆ initialize()

void QOhosFloatingWindow::initialize ( )

overridevirtual

Called as part of QWindow::create(), after constructing the window.

Platforms should prefer to do initialization here instead of in the constructor, as the platform window object will be fully constructed, and associated to the corresponding QWindow, allowing synchronous event delivery.

Reimplemented from QPlatformWindow.

Definition at line 121 of file qohosfloatingwindow.cpp.

References QOhosPlatformWindow::initialize().

Here is the call graph for this function:

◆ lower()

void QOhosFloatingWindow::lower ( )

Here is the caller graph for this function:

◆ raise()

void QOhosFloatingWindow::raise ( )

overridevirtual

Reimplement to be able to let Qt raise windows to the top of the desktop.

Reimplemented from QPlatformWindow.

Definition at line 92 of file qohosfloatingwindow.cpp.

References ownedViewOrNull(), and QOhosView::raise().

Here is the call graph for this function:

◆ requestActivateWindow()

void QOhosFloatingWindow::requestActivateWindow ( )

overridevirtual

Reimplement to let Qt be able to request activation/focus for a window.

Some window systems will probably not have callbacks for this functionality, and then calling QWindowSystemInterface::handleFocusWindowChanged(QWindow *w) would be sufficient.

If the window system has some event handling/callbacks then call QWindowSystemInterface::handleFocusWindowChanged(QWindow *w) when the window system gives the notification.

Default implementation calls QWindowSystem::handleFocusWindowChanged(QWindow *w)

Reimplemented from QPlatformWindow.

Definition at line 332 of file qohosfloatingwindow.cpp.

References QOhosPlatformWindow::requestActivateWindow().

Here is the call graph for this function:

◆ setGeometry()

void QOhosFloatingWindow::setGeometry ( const QRect & rect )

overridevirtual

This function is called by Qt whenever a window is moved or resized using the QWindow API.

Unless you also override QPlatformWindow::geometry(), you need to call the baseclass implementation of this function in any override of QPlatformWindow::setGeometry(), as QWindow::geometry() is expected to report back the set geometry until a confirmation (or rejection) of the new geometry comes back from the window manager and is reported via QWindowSystemInterface::handleGeometryChange().

Window move/resizes can also be triggered spontaneously by the window manager, or as a response to an earlier requested move/resize via the Qt APIs. There is no need to call this function from the window manager callback, instead call QWindowSystemInterface::handleGeometryChange().

The position(x, y) part of the rect might be inclusive or exclusive of the window frame as returned by frameMargins(). You can detect this in the plugin by checking qt_window_private(window())->positionPolicy.

Reimplemented from QPlatformWindow.

Definition at line 43 of file qohosfloatingwindow.cpp.

References ownedViewOrNull().

Here is the call graph for this function:

◆ setMask()

void QOhosFloatingWindow::setMask ( const QRegion & region )

overridevirtual

Reimplement to be able to let Qt set the mask of a window.

Reimplemented from QPlatformWindow.

Definition at line 313 of file qohosfloatingwindow.cpp.

References ownedViewOrNull(), and QOhosView::setWindowMask().

Here is the call graph for this function:

◆ setVisible()

void QOhosFloatingWindow::setVisible ( bool visible )

overridevirtual

Reimplemented in subclasses to show the surface if visible is true, and hide it if visible is false.

The default implementation sends a synchronous expose event.

Reimplemented from QPlatformWindow.

Definition at line 69 of file qohosfloatingwindow.cpp.

◆ startSystemMove()

bool QOhosFloatingWindow::startSystemMove ( )

overridevirtual

Reimplement this method to start a system move operation if the system supports it and return true to indicate success.

The default implementation is empty and does nothing.

Since: 5.15

Reimplemented from QPlatformWindow.

Definition at line 324 of file qohosfloatingwindow.cpp.

References ownedViewOrNull(), and QOhosView::startMoving().

Here is the call graph for this function:

◆ winId()

WId QOhosFloatingWindow::winId ( ) const

overridevirtual

Reimplement in subclasses to return a handle to the native window.

Reimplemented from QPlatformWindow.
