Zoom In/Out buttons invisible in internal GUI

Reported by: mvglasow Owned by: kazer
Priority: minor Milestone:
Component: port/wince Version: git master
Severity: Keywords:


When using the internal GUI on WinCE, the Zoom In/Out? buttons are invisible on startup. Tapping where the button should be will, however, start the desired zoom action and the buttons will appear. Also, bringing up the menu and returning to the map will show the buttons. Tested on WinCE SVN build 2952.

excerpt from my navit.xml:

<osd enabled="yes" type="button" x="0" y="32" command="zoom_out()" src="gui_zoom_out_32_32.png"/>
<osd enabled="yes" type="button" x="-32" y="32" command="zoom_in()" src="gui_zoom_in_32_32.png"/>

This also happens for me, but only sometimes! Haven't worked out a pattern yet.

I'm using latest SVN build 2964 on Ubuntu Karmic, Acer One netbook.

Looking at osd_core.c, I see that for pretty much all OSD items the init method ultimately calls the related draw method, EXCEPT for buttons. Is there any particular reason for this?

I suspect this missing call to be the culprit. tiiiim's symptoms may be because sometimes he's getting some events that would by themselves call osd_button_draw and the buttons will appear, sometimes there is no such event and the buttons hence will not appear.

Unfortunately I don't have a build environment set up, so I can't easily test this. Maybe someone with the build env can just drop a call to osd_button_draw into osd_button_init (at the very end) and see if that changes anything.
