* 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 |
|
* |
