For Canola we just have the window to not listen to mouse events, so it goes to the window below it, in this case our application. I can’t remember if we just disabled mouse events with some mplayer command line option or by reseting event mask of the window that we give for mplayer with -wid.

Anyway, if you opt to go with inputwin, it will work.

Thank you. What I really want is to create a window with mplayer in it. And when I click mouse, the play control panel appears. Like the behavior in canola.

Ouch! Seems that X does not send events to transparent areas!

Well, I actually like that behavior, can make some things handy, but I see that for your case it might be a problem.

Depending on what you want, you can create an input window with ecore_x_window_input_new(), it can be of size 1×1 but it will work if you grab input there. You can use e17 code for e_grabinput() as example. If you want real examples on how to get typed keys with modifiers and all, use /e/src/modules/conf_keybindings/e_int_config_keybindings.c since it does that.

the whole test1.edc file is

collections {
group {
name: “main”;
parts{
part {
name: “event_area1″;
type: RECT;
mouse_events: 1;
description {
state: “default” 0.0;
color: 0 0 0 0;
rel1 {
relative: 0.0 0.0;
offset: 0 0;
}
rel2 {
relative: 1.0 1.0;
offset: -1 -1;
}
}
}

}
}
}

something wrong with my last post. the window is all transparent but also cannot get mouse event.

I have create a rectangle area with mouse_event and this area covers all the window.

part {
name: “event_area1″;
type: RECT;
mouse_events: 1;
description {
state: “default” 0.0;
color: 0 0 0 0;
rel1 {
relative: 0.0 0.0;
offset: 0 0;
}
rel2 {
relative: 1.0 1.0;
offset: -1 -1;
}
}
}

but the rectangle is black.

It’s easy, just create a transparent rectangle (color: 0, 0, 0, 0). It can get events even without being visible, it just have to exist. Notice that window manager will still show border, you can set it to be borderless to avoid so.

Hi, I have tried your code. It’s very interesting. But I am puzzled how to make the transparent thing as a glass. That means the transparent thing will accept the mouse message but you cannot see it.
