How to create or move a window relative to the current desktop?x09
|
| Solution |
Find out the absolute location of the current console, and then the absolute location of your window.
Here is a fragment of code that saves your relative position:
x09
/*get absolute position of window's canvas, and frame dimensions*/
x09PtGetAbsPosition(window, &xpos, &ypos);
x09PtFrameSize(Ph_WM_APP_DEF_RENDER, 0, x09x09x09&leftwid, &tophgt, &rgtwid, &bothgt);
/*calculate absolute position of top left tip of the frame*/
x09windowX = xpos - leftwid;
x09windowY = ypos - tophgt;
x09/*get the current console's absolute coordinates*/
x09PhWindowQueryVisible(0, 0, 0, &console);
x09/*calculate relative position of the window within console*/
x09windowX -= console.ul.x;
x09windowY -= console.ul.y;
Given this, sorting out the "restore" is easy.
