How instruct to the Delphi IDE refresh the modified syntax highlight colors using OTA (Open Tools API)?

Question

I'm writting a plugin to integrate the Delphi IDE Theme Editor with the Rad Studio IDE (the current version of this tool run as an external application) so far everything is working fine (see the below image), except the fact which I can't figure out how refresh the selected syntax highlight colors in the Delphi IDE

Let me explain, in the standard option to change the syntax highlight colors (Editor Options-> Color) you can customize any element and assign a new foreground and background color, then if you press the . OK . button the IDE apply the changes and the IDE editor windows are updated with new settings.

Currently i can modify and store the new values, but I can't instruct to the Delphi IDE to apply the the new configuration, the changes are only visible if the IDE is restarted.

I searched the ToolsAPI unit and i found the IOTAEditOptions, IOTAHighlighter and IOTAHighlightServices interfaces but none it seems include an option to refresh (reload) the modified setting.

Also I tried unmangle (using tdump) and calling the functions of the coreide1XX.bpl file directly, but this did not work too.

How I can instruct to the Delphi IDE refresh the modified syntax highlight colors using OTA (Open Tools API)?

Let me know if you need more info or if the question is not clear.

Answer 1

A slight hack that should have the desired effect would be to have your plugin bring up the Environment Options dialog, and have the operator close it manually. This causes the IDE to reinitialize its configuration based on the submitted settings.

To do this, obtain a handle onto a Project (IOTAProject object) and call...

AProject.ProjectOptions.EditOptions;

Where AProject is defined as AProject: IOTAProject.

I know this isn't the most elegant of solutions, but if it has the desired effect, at least it's somewhat practical.

Answer 2

I'd say your best bet would be to snoop around coreide*.@Envoptions@TEnvironmentOptions@EditorSourceOptionsBeforeSave or coreide*.@Envoptions@TEnvironmentOptions@EditorSourceOptionsAfterSave

These get called when the Ok button gets clicked. I'm not very good at reading assembly but from the looks of it the environment options are loaded from the registery during IDE initialization and any changes made are written back as needed but the IDE depends on the in memory instance of TEnvironmentOptions to be the authoritative representation of all environment options.

coreide*.@Envoptions@TEnvironmentOptions@GetEdColors appears to be where the colors are retrieved from the environment options for editing by TEditorColor

It's unfortunate none of these classes is exposed to the OTA or NTA.
