Package motif has a few functions to allow easy access to Motif related
|
||
|
|
properties.
|
||
|
|
|
||
|
|
The main purpose here is that some applications communicate "no window
|
||
|
|
decorations" to the window manager using _MOTIF_WM_HINTS. (Like Google
|
||
|
|
Chrome.) I haven't seen Motif stuff used for other purposes in the wild for
|
||
|
|
a long time.
|
||
|
|
|
||
|
|
As a result, only the useful bits are implemented here. More may be added
|
||
|
|
on an on-demand basis, but don't count on it.
|
||
|
|
|
||
|
|
Try not to bash your head against your desk too hard:

||

|
||
|
|
|
||
|
|
Example
|
||
|
|
|
||
|
|
To test if a window wants decorations or not:
|
||
|
|
|
||
|
|
mh, err := motif.WmHintsGet(XUtilValue, window-id)
|
||
|
|
if err != nil {
|
||
|
|
log.Fatal(err)
|
||
|
|
} else {
|
||
|
|
log.Println("Decorations? ", motif.Decor(mh))
|
||
|
|
}
