Changing paragraph variables for selected area

mjsmithsr · Post by **mjsmithsr** » Mon Jul 16, 2012 5:14 pm

How do I change the formatting variables for paragraphs by assigning values through my program rather than through rvActionsResource.rvActionParagraph1? I want to be able to set the variables without forcing the user to enter the changes via the dialog.

Use ApplyParaStyleConversion procedure and OnParaStyleConversion event.
See the demo in Demos\*\Editors\Editor 2\

I had gotten that far but how do I set the actual values for the left indentation and the first line?

This demo has commands for increasing and decreasing the left indent: PARA_INDENTINC and PARA_INDENTDEC.
They are implemented in TForm1.rveParaStyleConversion in the following way:

Code: Select all

  PARA_INDENTINC:
        begin
          ParaInfo.LeftIndent := ParaInfo.LeftIndent+20;
          if ParaInfo.LeftIndent>200 then
            ParaInfo.LeftIndent := 200;
        end;
      PARA_INDENTDEC:
        begin
          ParaInfo.LeftIndent := ParaInfo.LeftIndent-20;
          if ParaInfo.LeftIndent<0 then
            ParaInfo.LeftIndent := 0;
        end;

You can implement similar commands for assigning specific values to ParaInfo.LeftIndent and ParaInfo.FirstIndent.
