PaintOne

Redraw a window and all windows above it

#include <Windows.h> Window Manager

void PaintOne( theWindow, badRgn );

WindowPeek theWindow ; window of interest

RgnHandle badRgn ; region affected

This low-level function is used by the Window Manager to build update

regions for a window and all windows in front of it.

theWindow is the WindowPeek (pointer to a WindowRecord) of the bottom-most

window needing to be updated.

badRgn defines a region that was adversely affected by some previous

operation.

Notes: This draws the window frame of theWindow and all windows above it

(which are affected). If some content of any such window has been

adversely affected, those regions are added to the update regions of each such

window.

Global variables SaveUpdate and PaintWhite are used by this function.

Since these flags are occasionally modified by the system, they should be set

or cleared before each operation:

SaveUpdate: TRUE = add badRgn to update region

FALSE = don't add the region

PaintWhite: TRUE = erase badRgn before adding to update region

FALSE = don't erase first.
