Disable this dialog when importing.

[Gabrielxd195]

Bug Summary

When you import a long sample or a heavy plugin, a small dialog box appears that freezes while the sample or plugin is opened, but if lmms freezes the dialog box stays on top of the other programs. This happens a lot on low-resource PCs.

Expected behavior

No dialog box appears when importing.

Affected LMMS versions

Versión 1.3.0-alpha.1.532+gc991a85ee (Linux/x86_64, Qt 5.9.5, GCC 7.5.0).

Have the same issue on Windows, so if you need confirmation that this isn't just a Linux problem

I am testing it on Linux, but this feature is specific to lmms and is in all operating systems.

That dialog is bugged. I've noticed it too, don't remember exactly what lines of code to look at. Might be good candidate for 1.3.

I'm inviting @regulus79 because they are looking at fixing Ui bugs rn and is active here.

hi :)

That dialog you are referring to is a TextFloat, defined in TextFloat.h, which is a widget that spawns when loading a sample/vst/whatever. Notably, it uses the QWindowFlags of Qt::ToolTip in its constructor. This causes it to remain on top of all windows, even windows not part of the application.

I was unsuccessful in trying to disable the Qt::WindowStaysOnTopHint, but I found online another person who was experiencing difficulties with the ToolTip window flag, and someone recommended that they use the Qt::Tool window flag combined with the Qt::FramlessWindowHint flag https://forum.qt.io/post/104793.

I tested everything by commenting out the line delete tf which removed the dialog after the loading. This allowed the dialog to stay up as long as I needed it to test its properties. I found that this solution did indeed solve the issue. However, in normal operation, my computer is fast enough that the tooltip does not appear. I would love if people could test #7613, particularly with large files or slower computers.
