Always open the "Add file" dialog on the same screen as the main window

[VanessaE]

Version

master branch, commit 4a90ab1

Operating system type + version

Debian 9.3, with XFCE 4.12 (in case the desktop environment matters)

Behavior

For me, no matter what I do, Slic3r insists on putting its "Add file " dialog on screen 1 (of 3), regardless of which screen Slic3r itself is on, usually screen 3). It even does this if screen 1 has a program running in full screen mode (e.g. watching a movie).

I guess Slic3r is passing some window manager hint to force this, but I have XFCE's window manager already set to open new windows wherever the cursor is.

For comparison, Pronterface's "Load" dialog behaves exactly as it should.

@YuSanka Would you please look into this annoying issue?
@FidelCapo would you please test, whether this behavior is Linux specific, or whether it is a general issue on all platforms? Thanks.

This doesn't happen on my Linux box. Slic3r is definitely not forcing this on purpose. Probably some kind of a mixup on the wxWidgets - GTK - window manager axis...

Do you have a similar issue with other applications on your XWindow system? Or is it just Slic3r. It looks to as like a general issue of your window manager.

[VanessaE]

It does happen on one or two other programs, but in most cases, new windows are opened where the pointer is - for example, I have a global keyboard shortcut to open a terminal, and it never goes to the wrong screen. The "open file" dialog presented by Chrome when I click "selecting them" at the bottom of this text editor widget (that is, Github's link to attach a file) also appears where it should.

Windows that open on the wrong monitor always end up waaaaaay over on the left monitor (out of 4 now). I assume it has to do with that monitor being both screen # 1 as far as X and XFCE are concerned, and being positioned at the far left in the desktop layout (thus having the lowest X coordinates).

Maybe windows that open on the wrong monitor either have, or lack, some important window manager hint or there's some artificial check/limit on placement coordinates or on screen number?

Hmm, I bet this is a general issue of wxWidgets on your particular Linux installation. Would you please provide us with the set of Slic3r PE dialogs that also open at a wrong screen, so we can deduce some pattern?

[VanessaE]

It only appears to affect the "Open STL/OBJ/AMF/3MF..." dialog (whether I call it up from the File menu or the "Add..." button), and the "Open 2.5D TIN mesh" dialog in the "File" menu.

All other dialogs open on the correct screen - print/printer/filament profiles, all four export options in the Plater menu, all of the File menu's items except the above, all of the relevant items in the right-click-on-the-part menu...

Sorry, we were not able to reproduce your issue on none of our Linux systems around. This must be some quirk of your setup I suppose. Closing.
