Automatically trim TRVLabelItemInfo

Hello RV-community!
I want to optimize the descendant of TRVLabelItemInfo so that the text always fits in a line. If there is too much text, I plan to put an ellipsis at the end (as in the photo). Can you tell me how to solve this problem?

Re: How to use Redo after TRVUndoList.AddInfo?

Yes, implementation of the TRVUndoModifyMathObject.Undo is here: procedure TRVUndoModifyMathObject.Undo(RVData: TRichViewRVData); var ItemInfo: TRVMathObjectItemInfo; begin if FItemNo > -1 then begin ItemInfo := TRVMathObjectItemInfo(RVData.GetItem(FItemNo)); if Assigned(ItemInfo) then begin ...

How to use Redo after TRVUndoList.AddInfo?

Hi, I have read other forum threads regarding "Custom Undo" operations, but I did not find an answer. Based on this topic , I implemented a custom Undo class, and it works fine: class procedure TRVUndoModifyMathObject.AddUndo(RVData: TRichViewRVData; ItemInfo: TRVMathObjectItemInfo); var Edit ...

TRVMathItemInfo.TextColor problem on existing objects

I have a problem with setting the TRVMathItemInfo.TextColor property. When the formula is created (a new one is added), this property works fine. But when the formula already exists and I try to change the TextColor, nothing happens. The same problem occurs with the visual formula editor ...

Re: Problem with STIX Math font

I commented the code and tested AME's solution. The fonts "STIXTwoMath-Regular.otf" and "STIXTwoMath-Regular.ttf" failed anyway (now the AV appears in a different place). It seems to me that the engine does not work properly with some characters, because the font "STIXTwoMath-Regular.input.ttf ...

Re: Problem with STIX Math font

I experimented a bit and this is what I found. The STIX font set includes several math fonts: - STIXTwoMath-Regular.otf (from the "fonts > static_otf" subfolder, 819 KB) - STIXTwoMath-Regular.ttf (from the "fonts > static_ttf" subfolder, 1483 KB) Both of these fonts result in an error (AV). But this ...

I don't use custom memory managers, but If we need a more detailed analysis, I am ready.

Problem with STIX Math font

Hi, I have a problem with the "STIXTwoMath-Regular" math font. It is a very common and functional font. But when I try to use it (just select from ComboBox in the Equation Editor), I get AV. I can't attach the font to this post, it's 819 kB. But you can download it freely here: https://github.com ...

Re: Access Violation when I press CTRL+A on the header

OK, I have already sent a letter with an example. It seems that this bug appears only if there is a table in the Header. I'm assuming that the table has a dynamic editor and catches the appropriate events, and that's where RVData=nil can be. To reproduce issue: 1. Set event handler for SRichViewEdit ...

Access Violation when I press CTRL+A on the header

Hi, I am getting Access Violation when I press CTRL+A on the header (TSRichViewEdit). Debugger shows that the property RVData=nil in the methods TCustomRichViewEdit.KeyDown and TCustomRichView.KeyDown. I set a temporary check at the beginning of the method: if RVData = nil then Exit; But perhaps a ...
