Member Function Documentation

◆ isActive()

bool KWin::MagnifierEffect::isActive ( ) const

overridevirtual

Overwrite this method to indicate whether your effect will be doing something in the next frame to be rendered. If the method returns false the effect will be excluded from the chained methods in the next rendered frame.

This method is called always directly before the paint loop begins. So it is totally fine to e.g. react on a window event, issue a repaint to trigger an animation and change a flag to indicate that this method returns true.

As the method is called each frame, you should not perform complex calculations. Best use just a boolean flag.

The default implementation of this method returns true.

Since: 4.8

Reimplemented from KWin::Effect.

Definition at line 288 of file magnifier.cpp.

◆ magnifierSize()

QSize KWin::MagnifierEffect::magnifierSize ( ) const

Definition at line 293 of file magnifier.cpp.

◆ paintScreen()

void KWin::MagnifierEffect::paintScreen	(	const RenderTarget &	renderTarget,
		const RenderViewport &	viewport,
		int	mask,
		const QRegion &	region,
		Output *	screen )

overridevirtual

In this method you can:

paint something on top of the windows (by painting after calling effects->paintScreen())
paint multiple desktops and/or multiple copies of the same desktop by calling effects->paintScreen() multiple times

In OpenGL based compositing, the frameworks ensures that the context is current when this method is invoked.

Reimplemented from KWin::Effect.

Definition at line 118 of file magnifier.cpp.

◆ postPaintScreen()

void KWin::MagnifierEffect::postPaintScreen ( )

overridevirtual

Called after all the painting has been finished. In this method you can:

schedule next repaint in case of animations You shouldn't paint anything here.

In OpenGL based compositing, the frameworks ensures that the context is current when this method is invoked.

Reimplemented from KWin::Effect.

Definition at line 185 of file magnifier.cpp.

◆ prePaintScreen()

void KWin::MagnifierEffect::prePaintScreen	(	ScreenPrePaintData &	data,
		std::chrono::milliseconds	presentTime )

overridevirtual

Called before starting to paint the screen. In this method you can:

set whether the windows or the entire screen will be transformed
change the region of the screen that will be painted
do various housekeeping tasks such as initing your effect's variables for the upcoming paint pass or updating animation's progress

presentTime specifies the expected monotonic time when the rendered frame will be displayed on the screen.

Reimplemented from KWin::Effect.

Definition at line 88 of file magnifier.cpp.

◆ reconfigure()

void KWin::MagnifierEffect::reconfigure ( ReconfigureFlags flags )

overridevirtual

Called when configuration changes (either the effect's or KWin's global).

In OpenGL based compositing, the frameworks ensures that the context is current when the Effect is reconfigured. If this method is called from within the Effect it is required to ensure that the context is current if the implementation does OpenGL calls.

Reimplemented from KWin::Effect.
