|
| And it is exactly what fvwm does. With
|
| AddToFunc immediate I echo immediate
| mouse 3 r n function immediate
|
| the "echo immediate" is executed as soon the button is pressed,
| and with
|
| AddToFunc click C echo click
| mouse 3 r n function click
|
| There are a couple of exception, though:
|
| - If an application is started that tries to grab control of the
| pointer, it will succeed only after the function is completed.
| - Commands that change the window focus do change the foucs
| immediately, but the window decorations are redrawn only after
| the function completes. Fvwm tracks the focused window by the
| corresponding X event, and events are not handled during
| function execution. Hence the delay.
| - To suppress excessive redrawing, changes in window styles are
| activated only after the function completes and fvwm is idle
| (i.e. not receiving events or module input).
| - If a command needs a window to operate on, and no window has
| been selected yet, you have to release the button first and
| then click on a window.
|
| Note that the function itself only completes when the last mouse
| button is released.

| Is there any chance your mouse or your X server is broken? When

Nope - I still get my old behavior. And I don't think I have anything wrong with
my X-server.

I use x11-base/xorg-x11-6.7.0-r2
