GetPaintDC

DataWindow expression function

Description

Returns the GDI context to which to draw.

Syntax

GetPaintDC ( )

1	GetPaintDC ( )

Return value

UnsignedLong.

Usage

The clip region of the GDI context is guaranteed to be the same as
the rectangle defined by GetPaintRectHeight, GetPaintRectWidth,
GetPaintRectX, and GetPaintRectY.

You can also use the GetClipBox GDI function. You can compute the
bounds inside the global rendering function itself.

The GetPaintDC expression is only valid in the context of the
Paint expression function.

Examples

This example draws a cube with the text of the column
emp_lname.

Paint

     MyDrawWPFCubeText
     (
          GetPaintDC(),
          GetPaintRectX(),
          GetPaintRectY(),
          GetPaintRectWidth(),
          GetPaintRectHeight(),
          emp_lname,
