working with the input().pointer, in particular button states

[strasdat]

I'm working on some mouse gestures and trying to use input().pointer.

However, the following returns always false no matter whether the mouse button is pressed or not:

println!("{}",   egui_ctx.input().pointer.primary_down());

(I also tried secondary button, middle button etc...)
Apart from this, my mouse buttons work just fine in egui and elsewhere.

Possibly I'm using the api wrong. How can I detected whether a mouse button (left vs right) is down?

However, other aspects of the pointer api works just fine. E.g. I can detect and print out delta mouse motion:

println!("left {} {}", egui_ctx.input().pointer.delta().x, egui_ctx.input().pointer.delta().y);

Example output:

0 -1
26 -23
42 -26
99 -52
46 -19
105 -43
66 -29
114 -61

Okay, I tested it on windows mouse button is actually registered. Before I did run on linux.

Edit: Okay, the problem was in front of the keyboard.

Not a problem linux vs. windows. When trying to figure mouse interactions out in egui-minigui, I accidentally deleted the following line which seems to propagate mouse events from minigui to egui::

    self.egui_mq.mouse_button_down_event(ctx, mb, x, y);
