wrong DPI setting used on macOS Retina display until Apply clicked in Preferences

[denniscote]

dlangide uses 96 DPI for screen display when started on macOS using dmd and dub installed by Homebrew, and then the following dub commands to install and run dlangide. Note the user must manually install SDL2 in Homebrew before dlangide will build correctly.

dub install dlangide dub run dlangide

All text and icons are displayed very small. Open the Preferences dialog and you will see the screen resolution is displayed as "Use Screen DPI (192)", but the text and icons are displayed using 96 DPI until the user clicks the Apply button in the Preferences dialog.

The other screen resolution settings in the Preferences dialog can be used to verify the initial display is actually at 96 DPI.

I also noticed that the check boxes in the Text Editors and Common panes of the Preferences dialog look like they are always displayed at 96 DPI (ie very small size) even after the rest of the UI has changed to use the 192 DPI setting. They remain very small,

Could you please attach ui.log of DlangIDE starting (while option override screen dpi is disabled - set to default). Use debug build - w/o --build=release dub run dlangide 2> ui.log

I hope this is what you are looking for.

I noticed it detects the resolution as 108 DPI but the actual resolution is 218 DPI as reported by MacTracker for my iMac.

Thank you! I hope this will help me to prepare a fix.

I tried the latest dlangide code from git and got several deprecation warnings. See dlangide.log file attached. This version reports as v0.8.10 when started.

dlangide.log

I also noticed that the button icons on the toolbar are not resized when the screen resolution is changed to 300 DPI to make the menu and console text large enough to read. See the screen capture file attached. These buttons remain too small to be used.

I also attached a log of dlangide starting up a second time after the initial build. See file dlangide2.log attached.

dlangide2.log

I would like to try to help with the dlangide/dlangui development if I can. I'm fairly new to D but have been programming for many years in C and C++. I'm skimming through the dlangide source files to see what I can figure out.

Yes there are some hdpi issues you can read more about it here: https://github.com/buggins/dlangui/issues/529.

I think most D programmers are new ;) Reading D code is much easier than C++. I am waiting for your first PR :)
