RvFontCombobox behavior with multiple fonts

Hello RichView Support,
I have a question regarding the behavior of the RVFontComboBox.
In Microsoft Word, when selecting text that contains two or more different fonts, the font combo box appears empty, indicating mixed formatting.

In RichView, however, when I replicate this scenario, one of the fonts is always displayed instead. The selected font depends on the direction of the selection:
- When selecting from top to bottom, the last font is shown.

- Top to Bottom.png (24.01 KiB) Viewed 4976 times
- When selecting from bottom to top, the first font is shown.

Is there a way to replicate the behavior of Microsoft Word, so that the combo box indicates mixed fonts instead of displaying a single one?
Kind regards,
Tom

I used this code to do something like that:
Code: Select all
var
fi, fi2: TFontInfo;
i, FStart, FSOff, FEnd, FEoff: integer;
rv: TCustomRichViewEdit;
...
rv.GetSelectionBounds(FStart, FSOff, FEnd, FEoff, true);
fi := rv.Style.TextStyles[rv.GetItemStyle(FStart)];
for i := FStart to FEnd do
begin
fi2 := rv.Style.TextStyles[rv.GetItemStyle(i)];
if fi.FontName <> fi2.FontName then
begin
cmbFontName.Text := '[Multiple]'; //or you could set to nothing
break;
end;
end;
As far as I know, there's no other way other than to spin through your selection (you might have a different font in the middle of the selection, not just at the start or end). Keep in mind if you have a huge file and select it all, this can be slow. I stopped using it as I decided I didn't need it.

These combo-boxes display the font of the current text style.
Yes, it was done for performance reasons.

Hi,
Thank you both for your responses.
I will keep it that way then.

Hi Sergey,
As you mentioned the current text style, I'm reporting a bug that can be reproduced in the demo.
Please enter the following text:
This is a text. This is another sentence
This is a new line

Now select "another sentence" and change the font (I used Webdings).

- Font Changed.png (3.53 KiB) Viewed 4698 times
After that, select the entire text. The font combo box will display the default font.

- Change Font Back.png (11.71 KiB) Viewed 4698 times
Now click into the font combo box and press Enter. As a result, the entire text changes to Webdings.

Shouldn’t it revert to the default font instead?

When you select a symbol font, RichViewActions auto-apply SYMBOL_CHARSET.
I agree, they should change SYMBOL_CHARSET to DEFAULT_CHARSET when applying a non-symbol font.
I will be implemented in the next update.

It turned out that the problem is different. Although the combo box text is "Arial", its ItemIndex still points to the "Webdings" item. I'll fix applying the selected font when pressing Enter in the next update.
