* Name: nxtk_toolbarbounds
|
||
|
|
*
|
||
|
|
* Description:
|
||
|
|
* Return a bounding box that contains the toolbar in the coordinates of
|
||
|
|
* the containing, framed window. For example, the recturned origin
|
||
|
|
* (rect.pt1) is the offset toolbar in the framed window.
|
||
|
|
*
|
||
|
|
* NOTE: This function is unsafe in the case of the multi-user NX server
|
||
|
|
* where the width of the window may be being changed asynchronously! It
|
||
|
|
* may return the old size in this case.
|
||
|
|
*
|
||
|
|
* Input Parameters:
|
||
|
|
* hfwnd - The handle returned by nxtk_openwindow
|
||
|
|
* bounds - User provided location in which to return the bounding box.
|
||
|
|
*
|
||
|
|
* Return:
|
||
|
|
* OK on success; ERROR on failure with errno set appropriately
|
||
|
