I'm trying to determine the actual pixel dimensions of my Android device. In order to get the real height, it seems I need to first call "systemui 0x1e02" The problem is that "borg systemui" returns immediately, but hasn't yet completed. Here is an example that shows this problem. I get two different screenheights: "1504" and then one second later: "1600" ------------------ borg systemui 0x1e02 puts [winfo screenheight .] after 1000 {puts [winfo screenheight .]} vwait forever ------------------ Might it be possible to have some way to know that systemui has completed? If not, I can work around this (slight) problem by waiting 500ms. chw added on 2016-05-20 21:25:13: (text/x-fossil-plain) Even if the SystemUI.setSystemUI run on the UI thread is synchronized with the caller (Tcl code) it is carried out asynchronously. A better approach might be to "bind . <<ViewportUpdate>>" or (when your toplevel is in fullscreen mode) to "bind . <Configure>" and to watch out for "winfo screenheight" in the bound code. chw added on 2019-10-11 19:01:24: (text/x-fossil-plain) The problem is most likely a designed feature by the Android framework. And thus impossible to be solved. Therefore, closing this ticket. |
