Yes.

I tested this one:
does not work under macOS.

Under Debian it works as expected with wxWidgets 3.2.4
Should I report this as macOS bug?

PS: Under Windows its also OK.

The file is not hidden and is showed in the dialog but is not selectable; Greyed out.
I only tested this under macOS, but I will test now under Debian and will report.

I'm trying to filter files for a wxFileDialog like this: wxT("AMP (*.amp)|*.amp|IOScript (*.io)|*.io|LEDScript (*.led)|*.led|Crontab (crontab)|crontab") The first three filter does work as expected, but the "crontab" files are not selectable. How can I filter a filename? What I h...

In the latter case I could save the wxGraphicsContext and create it only once.

Not possible: Crash.

the display scaling factor is two decimal digits

Thanks; I corrected this.

the redraws of individual items being observable when e.g. scrolling

This effect is only under Windows; GTK and macOS are OK.
It seems that Windows does not like a lot of windows.

The Display geometry and scaling are retrieved from wxWidgets: int displays = wxDisplay::GetCount(); char* displayText = NULL; for( int i = 0; i < displays; i++ ) { wxDisplay display((unsigned int)i); wxRect rect = display.GetGeometry(); int w = rect.width; int h = rect.height; double sf = 1.0; #if ...

The ZIP installer has a workspace with the Demo plan.

For instructions:

But its very easy:
1) download
2) unzip
3) d-click on desktoplink.cmd

Click on the Desktop icon and open the demo workspace.

It's probably too late to change your approach now, That would mean a major rewrite for the graphical part of the application. To draw all objects on the same canvas is not very object orientated but could be an alternative, but the performance penalty only pops up under Windows with scaling > 100%...

Are you saying that every single small square here is its own window?

Only the once with a symbol on it. Empty grid squares are empty.
Depending on the object type the popup menu is different and a click or D&D behaves different.

parsing the SVG during drawing instead just once when loadin if you do not read my post completely... I wrote that the SVG's are parsed and FromDIP's only one at starting up the application. Every SVG represents an object and has its own wxWindow on the main panel. Also the drawing takes place on i...

Now I will test with the extra configure option for D2D: --enable-graphics-d2d

this option makes it even worse.
