This is driving me crazy! Here's my code (inside a large macro):
// set Gui.IconPath char tmp[1024]; sprintf(tmp,"%s:%s",getenv("HOME"), gEnv->GetValue("Gui.IconPath",".")); assert(strlen(tmp)<sizeof(tmp)); // snprintf() not available gEnv->SetValue("Gui.IconPath",tmp);printf("Gui.IconPath='%s'\n",gEnv->GetValue("Gui.IconPath","."));
window = new TGMainFrame(gClient->GetRoot(),200,200, kVerticalFrame); window->SetIconPixmap("historooticon.png");
Here's the output on Linux:
Gui.IconPath='/home/tjrob:/home/tjrob/icons:/home/tjrob/root/icons:.' root [1] .!ls -l /home/tjrob/historooticon.png -rw-r--r-- 1 tjrob tjrob 591 Sep 10 11:56 /home/tjrob/historooticon.png
That output looks fine, BUT I GET THE WRONG ICON (the default X-windows "X").
If I copy historooticon.png to either /home/tjrob/root/icons or "." then I get the correct icon.
What is going on? Why doesn't it use the updated Gui.IconPath?
