Detailed Description

Window non-rectangular shape support.

Window shape is defined with the array of points that should be modified at every resize of the window. The derived window should modify the shape points array by ovewriting shapeResize() method. The window resize support is activated only if window resizable() is true.

Constructor & Destructor Documentation

sptk::CWindowShape::CWindowShape

(

sptk::CWindow *

window

)

Constructor.

Parameters:

window

sptk::CWindow*, window to change shape

Member Function Documentation

void sptk::CWindowShape::changeSize	(	int	mouseX,
		int	mouseY
	)			[protected]

Resizes the window based on mouse zone and mouse screen coordinates.

Parameters:

	mouseX	int, mouse x-coordinate in the screen
	mouseY	int, mouse y-coordinate in the screen

void sptk::CWindowShape::initShapeExtension

(

)

[protected]

Initializes shape extension.

Allows window to use shape extension. Should be called before the window is first shown.

int sptk::CWindowShape::mouseZone	(	int	mouseX,
		int	mouseY
	)			const [protected]

Computes mouse zone from window coordinates.

Parameters:

	mouseX	int, mouse x-coordinate in the window
	mouseY	int, mouse y-coordinate in the window

virtual int sptk::CWindowShape::shapeCursorHandle

(

int

event

)

[protected, virtual]

Changes the window cursor based on the mouse position in the window.

Designed to emulate cursor changes on the window border for shaped windows. Should be uncoditionally called inside handle() for the window.

virtual void sptk::CWindowShape::shapeResize	(	int	w,
		int	h
	)			[inline, protected, virtual]

Shape resize.

This method should be overwritten in the derived class to adapt m_shapePoints[] to the window size.

Referenced by resizingShape().

bool sptk::CWindowShape::shapeResizing

(

)

[inline]

Returns true if the window is resizing as a result of border drag.

Can be used to simplified drawing during the resize

References m_resizingZone.
