GExperts stores its settings in the Windows registry, under a key that is specific to each installed Delphi version. Copying that configuration to another machine, or from one Delphi version to another, used to mean exporting registry keys by hand and editing them so they pointed at the right version and then importing them into … Continue reading GExperts: Export and Import Your Complete Configuration

New GExperts Expert: A Tabs Menu for Delphi 6 to 10.2
Recent versions of Delphi (starting with Delphi 10.3 Rio) have a "Tabs" entry in the main menu that lists the files currently open in the editor and lets you jump to any of them.

New in GExperts 1.3.26: Auto Switch Desktop
At the Pascal Conference 2025 in Sundern Heiko Rompel (kralle) made a presentation about a plugin (or was it a patch?) for Lazarus that automatically switched between two desktop layouts whenever you toggled between the form designer and the code editor with F12. The reasoning was simple: some windows, such as the Object Inspector, are … Continue reading New in GExperts 1.3.26: Auto Switch Desktop
Delphi VCL: Owner drawing a TStringGrid
Embarcadero has broken owner drawing of TStringGrid several times. To get the text positioned correctly you need version-specific X and Y offsets. Here is the case statement GExperts uses (from GX_StringGridDrawFix.pas): [delphi] procedure DetermineTextOffsets(_Focused: Boolean; out _XOffset, _YOffset: Integer); begin case GetBorlandIdeVersion of ideD600..ideRSXE1U1: begin // Versions before XE2 worked fine with an offset of … Continue reading Delphi VCL: Owner drawing a TStringGrid
Delphi desktop settings revisited
I blogged about how and where Delphi stores the desktop settings before. Back then I described the values as percentages of "the monitor" without being precise about which monitor and exactly which area. Since then I have nailed down the details. This applies to at least Delphi 12. The "percentage" values given in the file, … Continue reading Delphi desktop settings revisited
