1) You can disable all RichViewActions by assigning False to RVAControlPanel.ActionsEnabled

That's no good for me, because I want to be able to disable a specific action only.

2) You can disable the given RichView-action by assigning True action.Disabled.

Ah, yes - I missed that one! Thanks!

I have a few special situations, where I need to disable some of the actions, even though they are enabled by default. For example, I'd like to prevent insertion of a page break in a paragraph with a certain style. I tried simply writing the OnUpdate handler but then the default handling is complete...

because user can't destroy a good built table by unconcentrated working. If user want to resize col (or row) he must do it fully aware of importance.

Well, that's why the "undo" command is there for!

Is there a way to show the caret only when there is no selection? I'm thinking something along the lines of what Word does. I guess HideCaret/ShowCaret would be the way to go - the problem is where to put those calls to trap selection changes? OnSelect seems to be the place, but it fires far too oft...

Interesting! I'll need to investigate if everything works the same. Thanks for putting this demo together!

Well, I'm happy to say that the ScrollParent idea appears to be working smoothly!

If you'd be interested to review the changes and include these modifications into main source, let me know and I'll send you the modified RVScroll.pas.

If not, that's ok, too.

I'm actually toying with the idea to modify TRVScroller implementation by adding a property ala ScrollParent: TWinControl. If this property is assigned TRVScroller would display scrollbars on this control instead on itself.

What do you think?

I'm trying to implement a Word-like page layout for RVE and I need a way to implement my own scrollbars, because they need to be detached from the actual editor. I'm having problems synchronizing my custom scrollbars with the actual editor scrolling, because I can't access all the necessary values o...

Ah, so simple now. It used to be fairly complicated.

Thanks!

Can someone please show me what must be done to make the blue selection rectangle always be as high as the tallest item in selection (like MS Word does)? By default, rectangle height varies from item to item. I know it's possible, because I asked this very same question a few years back, when I firs...

After digging through the source, I found a way to detect the situation. In OnItemAction I check Sender.Focused value. If it's False, then the event is a result of inplace editor being filled with cell contents. If it's True, then it's a genuine event. The question remains if this check will still w...

I noticed that OnItemAction fires with ItemAction = rviaInserting when clicking inside a cell if caret was previously outside. I figure this happens because of the trick with a nested inplace editor, which comes transparently to life when a cell is being edited. However, for all practical purposes t...

Hm, yes - those are both good points. But that can't happen with items that have style protection enabled, right? And it just so happens I only need to know when those items are being deleted. I don't care about the others.

Actually, I just found out that OnItemAction event is close enough for my needs. It can catch every item before it gets deleted or cut.

Aleksander

Is there a clever way of detecting a selection deletion before it occurs?
