.SH DESCRIPTION
|
| 35 |
|
|
.PP
|
| 36 |
|
|
In general, a window should never set its own position; this should be
|
| 37 |
|
|
done only by the geometry manger that is responsible for the window.
|
| 38 |
|
|
For top-level windows the window manager is effectively the geometry
|
| 39 |
|
|
manager; Tk provides interface code between the application and the
|
| 40 |
|
|
window manager to convey the application's desires to the geometry
|
| 41 |
|
|
manager. The desired size for a top-level window is conveyed using
|
| 42 |
|
|
the usual \fBTk_GeometryRequest\fR mechanism. The procedure
|
| 43 |
|
|
\fBTk_MoveToplevelWindow\fR may be used by an application to request
|
| 44 |
|
|
a particular position for a top-level window; this procedure is
|
| 45 |
|
|
similar in function to the \fBwm geometry\fR Tcl command except that
|
| 46 |
|
|
negative offsets cannot be specified. It is invoked by widgets such as
|
| 47 |
|
|
menus that want to appear at a particular place on the screen.
|
| 48 |
|
|
.PP
|
| 49 |
|
|
When \fBTk_MoveToplevelWindow\fR is called it doesn't immediately
|
| 50 |
|
|
pass on the new desired location to the window manager; it defers
|
| 51 |
|
|
this action until all other outstanding work has been completed,
|
| 52 |
|
|
using the \fBTk_DoWhenIdle\fR mechanism.
