GTK+ widgets/windows being (randomly) corrupted, with what seems to be timers.
- by nubela
Hi,
I have recently implemented a scrolling text across an area of limited screen estate using a timers repeating every 100ms, and some simple string appending.
However, after this very implementation, I have come to realise that my GUI is getting randomly bugged/corrupted after a certain while. That is to say that some widgets/windows become completely white, and eventually the entire GUI turns white and unclickable.
What is weird is that there is no error debug output at all.
Having said that, I am using Mono with GTK-Sharp for the application. Does anyone have an idea or a possible clue how and why this is happening?
If not, how can I further debug this properly?
Thanks, really appreciate it.
PS: Sometimes, it takes up to 1.5 hours for the thing to start corrupting, it has random timeframes for it to start happening.
This is my the code implemented that caused this issue:
void ScrollSyncTo(object sender, System.Timers.ElapsedEventArgs e)
{
//initial check if it fits nicely alr
if (sync_to_full_txt.Length <= sync_to_max_char)
{
sync_to_timer.Stop();
return;
}
//check for pause
if (sync_to_pause >= 0)
{
sync_to_pause--;
return;
}
//check direction
int temp_psn;
string temp_str;
if (sync_to_direction)
{
temp_psn = sync_to_posn + 1;
if (sync_to_full_txt.Substring(temp_psn).Length < sync_to_max_char)
{
sync_to_pause = sync_to_break_steps;
sync_to_direction = false;
sync_to_posn = sync_to_full_txt.Length - 1;
System.GC.Collect();
return;
}
else
{
temp_str = sync_to_full_txt.Substring(temp_psn, sync_to_max_char);
}
}
else
{
temp_psn = sync_to_posn - 1;
if (temp_psn + 1 < sync_to_max_char)
{
sync_to_pause = sync_to_break_steps;
sync_to_direction = true;
sync_to_posn = 0;
System.GC.Collect();
return;
}
else
{
temp_str = sync_to_full_txt.Substring(temp_psn - sync_to_max_char + 1, sync_to_max_char);
}
}
//lets move it
sync_to.Text = temp_str;
sync_to_posn = temp_psn;
}
