Open IDE in DPI Unaware??

[Ian Branch 127]

Hi Team,

D11.3.1. Win 11.

When I double click on a Delphi file in Windows Explorer, it opens in Delphi IDE in DPI Aware mode.

Is there someway to make Windows or Delphi open the IDE in DPI Unaware mode when I double click on a Delphi file fromthe File Explorer?

Regards & TIA,

Ian

You can do that with the command line parameter "/highdpi:unaware". That won't work with just a double click from Explorer, though.

 

I have different links on my desktop to quickly choose between both behaviors.

An aside, but what would be the reasons for running the IDE dpi unaware?

Old Age, Eye Sight, etc.  🙂  The forms are too small for me to work with on 4k monitor when Delphi opens dpi aware.

Yes, that is fair. I'm tempted to get a third monitor to run at 96dpi for that purpose!

Do that. It's lots of fun discovering all the new bugs in the IDE that creep up in that scenario. For bonus points make the 96dpi monitor our main monitor.

I wish the IDE could have a zoom option when displaying/editing forms.

Not even if you edit the Registry to add that command-line parameter to the file association that launches the IDE?

[Uwe Raabe 2057]

That may indeed be possible, but will probably turn out a bit tedious. It also doesn't have the flexibility to choose between both options.

 

A more simple way could be to edit the compatibility settings for bds.exe and force high dpi support to one of the System values, but that also misses the flexibility.

 

My personal favorite are the mentioned desktop links. Not only does it allow to quickly start Delphi in the desired mode, also dragging a Delphi file onto one of those also opens the file with the appropriate settings. Besides the dpi selection, I use this scheme for quite a while to handle different registry keys for Delphi.

One could also register a different program that simply calls bds.exe with the desired parameter.

You could load a second copy of Delphi as a tool in tool options.

This turned out to make the Object Inspector unusable - better don't try this.

Yup it works, but it isn't perfect, yet.  😉
