wx.RegionIterator — wxPython Phoenix 4.2.4a1 documentation

This class is used to iterate through the rectangles in a region, typically when examining the damaged regions of a window within an OnPaint call.

To use it, construct an iterator object on the stack and loop through the regions, testing the object and incrementing the iterator at the end of the loop.

See wx.PaintEvent for an example of use.

Inheritance diagram for class

:

__init__

Default constructor.

GetH

An alias for GetHeight .

GetHeight

Returns the height value for the current region.

GetRect

Returns the current rectangle.

GetW

An alias for GetWidth .

GetWidth

Returns the width value for the current region.

GetX

Returns the x value for the current region.

GetY

Returns the y value for the current region.

HaveRects

Returns True if there are still some rectangles; otherwise returns False.

Next

Move the iterator to the next rectangle in the region.

Reset

Resets the iterator to the beginning of the rectangles.

__bool__

Returns True while there are still rectangles available in the iteration.

__nonzero__

Returns True while there are still rectangles available in the iteration.
