I have a problem using C::B on Mint 19.1.

It doesn't matter which version of C::B I'm using (16.x from repo, 17.x installed as.deb, self-built), it's always the same.

Problem descrition:
C::B Always hangs forever if I close it. I started it from console, to get some details.

How to reproduce:
- Start C::B, close it, reproduces 100% of the time for me.

Here's the startup trace shown if my self-built (r11579) executable is used.

Tell me if more information is needed.

Can you start cb under a debugger and post the backtrace? Press ctrl-c and execute the bt or thread apply all bt command.

[Simon]

I found the problem, it was caused by my 3-Monitor setup.
I've got 3 Monitors (1 is a TV) @1920x1080p, which where sorted left(TV)-middle(primary)-right.
Usually the TV is turned off, I use the middle monitor most, I also used it for C::B. When I closed it, the "Perspective has changed...." dialog was shown, but it was not visible to me because it poped up on the TV... So for me the GUI was frozen and didn't react anymore.

The real problem is imo that this dialog (maybe others aswell?) don't check for the current Monitor where the C::B Mainwindow is currently running, and therefore might pop up on another screen.

[Teodor Petrov]

Interesting. How do you do your monitor setup? I'm not really familiar with AMD cards. Can you post the xrandr settings or anything that should the arrangement of monitors in X?

Are you able to rebuild codeblocks applying patches, so you can test fixes?

[Simon]

I've made a startup shell script, containing the following 2 lines:
xrandr --output DVI-D-1 --mode 1920x1080 --rate 60 --output HDMI-1 --same-as DVI-D-1
xrandr --output DVI-D-2 --right-of DVI-D-1

Without that, as it was when I got the problem with C::B, the monitors are arranged as follows: (I'll also add an attachment, with a screenshot from the GUI settings menu for Monitors)

xrandr --listmonitors 
Monitors: 3
 0: +*DVI-D-1 1920/531x1080/299+1920+0  DVI-D-1
 1: +HDMI-1 1920/1600x1080/900+0+0  HDMI-1
 2: +DVI-D-2 1920/477x1080/268+3840+0  DVI-D-2

How do you mean "applying patches"? Just replace some Source code files with others & make a rebuild? If so, sure.

If you wish, we could switch the discussion to PM, and keep it clean here & just put updates here.

[Teodor Petrov]

Is the TV set as the main/default monitor?

And yes - applyuing patches means replace some source code and do rebuild.

I'll try to make a fix in the next days if after 5 day you don't hear from me, then don't hesitate to ping me.

[Simon]

No, the TV is not the default monitor. However, a lot of software opens up there, I think this is because its the left monitor and maybe because it's connected by HDMI.

Just let me know if you have found sth, I'll rebuild & test then :)

[Teodor Petrov]

BTW: What happens if you press alt-g does the search dialog open on the correct monitor? Have you checked the multi-monitor related settings in Settings -> Environment (the won't help for the dialog for the layout, just yet)?

[Simon]

Just deleted the Cache of my C::B, to get the first launch wizard again.

• The Initial Window for selecting the compiler opens on the wrong Monitor aswell (Also on the TV), but that's okay, because I see the new window is open in the taskbar, and can simply move it using Super+LShift+Right.
• When using Alt+g, it opens on the correct monitor.
• When Closing, the "Perspective has changed...."-dialog is (as before) on the wrong Monitor (TV), but I can also move it using Super+LShift+right, however, If I didn't know about that dialog, I can't see it, because it doesn't show up as an additional window on the taskbar icon.

After closing Codeblocks properly, and starting again, the Mainwindow starts on the primary monitor as intended. However, when closing, the "Perspective has changed...." dialog is AGAIN on the TV, the Alt+G window is still correct.

Conclusion: Not all C::B windows do behave consistant, e.g. the "Select File"-dialog (opened via Alt+g) does work properly, the "Perspective has changed...."- dialog does not.

Edit:

When enabling the "Enhanced Multi Monitor Dialog placement" in Settings->Environment->View (I guess that's what you mean), then it all seems to behave correctly, as far as i just found out now.

[Teodor Petrov]

Thanks for testing this.

I guess that for the well behaved windows we're calling PlaceWindow and we're not calling it for the others.

[Simon]

Hm, seems legit. But I'm questioning myself than: Why is that option not enabled by default? Or, e.g. If C::B detects multile monitors on (first) startup?

[Teodor Petrov]

What option? If the call to PlaceWindow is missing the option is useless as far as I know.

[Simon]

I mean, if the "Enhanced Multi Monitor Dialog placement" in Settings->Environment->View is enabled, the problem seems to be solved, so I don't know why this option is not enabled by default?

[Teodor Petrov]

20.03 or newer should have this option default to "Center On Parent", so I think this ticket could be closed. If 20.03 or newer doesn't work as expected please let me know.
