詳細描述

The QWaylandXdgToplevel class represents the toplevel window specific parts of an xdg surface.

此類屬於 QWaylandXdgShell extension and provides a way to extend the functionality of an QWaylandXdgSurface with features specific to desktop-style windows.

It corresponds to the Wayland interface xdg_toplevel .

QWaylandXdgToplevel:: QWaylandXdgToplevel ( QWaylandXdgSurface * xdgSurface , QWaylandResource & resource )

構造 QWaylandXdgToplevel 為給定 xdgSurface and resource .

[override virtual] QWaylandXdgToplevel:: ~QWaylandXdgToplevel ()

Destroys the instance of QWaylandXdgToplevel. The destructor is virtual.

QWaylandXdgToplevel::DecorationMode QWaylandXdgToplevel:: decorationMode () const

[signal] void QWaylandXdgToplevel:: decorationModeChanged ()

[static] QWaylandXdgToplevel *QWaylandXdgToplevel:: fromResource ( ::wl_resource * resource )

返迴 QWaylandXdgToplevel corresponding to the resource .

[static] QWaylandSurfaceRole *QWaylandXdgToplevel:: role ()

Returns the surface role for the QWaylandToplevel.

void QWaylandXdgToplevel:: sendClose ()

Sends a close event to the client. The client may choose to ignore the event.

注意： 此函數可以被援引，通過元對象係統和從 QML。見 Q_INVOKABLE .

uint QWaylandXdgToplevel:: sendConfigure (const QSize & size , const QVector < QWaylandXdgToplevel::State > & 狀態 )

Sends a configure event to the client. Parameter size contains the pixel size of the surface. A size of zero means the client is free to decide the size. Known 狀態 are enumerated in QWaylandXdgToplevel::State .

uint QWaylandXdgToplevel:: sendConfigure (const QSize & size , const QVector < int > & 狀態 )

注意： 此函數可以被援引，通過元對象係統和從 QML。見 Q_INVOKABLE .

uint QWaylandXdgToplevel:: sendFullscreen (const QSize & size )

Convenience for sending a configure event with the fullscreen state set, and maximized and resizing removed. The activated state is left in its current state.

size is the new size of the window.

注意： 此函數可以被援引，通過元對象係統和從 QML。見 Q_INVOKABLE .

另請參閱 sendUnmaximized .

uint QWaylandXdgToplevel:: sendMaximized (const QSize & size )

Convenience for sending a configure event with the maximized state set, and fullscreen and resizing removed. The activated state is left in its current state.

size is the new size of the window.

注意： 此函數可以被援引，通過元對象係統和從 QML。見 Q_INVOKABLE .

uint QWaylandXdgToplevel:: sendResizing (const QSize & maxSize )

Convenience for sending a configure event with the resizing state set, and maximized and fullscreen removed. The activated state is left in its current state.

maxSize is the new size of the window.

uint QWaylandXdgToplevel:: sendUnmaximized (const QSize & size = QSize(0, 0))

Convenience for sending a configure event with the maximized, fullscreen and resizing states removed, and fullscreen and resizing removed. The activated state is left in its current state.

size is the new size of the window. If size is zero, the client decides the size.

注意： 此函數可以被援引，通過元對象係統和從 QML。見 Q_INVOKABLE .
