Disabling Actions during a function then restoring.

Greetings,
I have a lot of select then work with text in a big function and I would like to disable the updating of all the Font Combos, sizes etc. that are through RVAControlPanel.
I've tried ActionsEnabled := False before the function then ActionsEnabled := True after the function.
But it does not seem to do what I need. I still see the interface updating. Ideas.... ???

But assigning RVAControlPanel.ActionsEnabled = False really disables all RichViewActions.
However, if you call the function like this:
Code: Select all
RVAControlPanel1.ActionsEnabled := False;
Sleep(1000);
RVAControlPanel1.ActionsEnabled := True;
you will not see that buttons are disabled for a second. It's because actions were not be able to update their states.
We can do it manually:
Code: Select all
RVAControlPanel1.ActionsEnabled := False;
for i := 0 to ActionList1.ActionCount - 1 do
ActionList1.Actions[i].Update;
Sleep(1000);
RVAControlPanel1.ActionsEnabled := True;
Still no effect. It's because, while actions were updated, toolbars were not repainted.
So we repainting them:
Code: Select all
RVAControlPanel1.ActionsEnabled := False;
for i := 0 to ActionList1.ActionCount - 1 do
ActionList1.Actions[i].Update;
ToolBar1.Repaint;
ToolBar2.Repaint;
ToolBar3.Repaint;
Sleep(1000);
RVAControlPanel1.ActionsEnabled := True;
This code works. But not If this code is not called from a toolbar's button OnClick.
It works for all toolbars but not for a toolbar that contains a button that executes this code.
The problem can be solved by using PostMessage. Let me know if you need explanation how to do it.

Greetings Sergey,
Excellent thank you.
Do you have any recommendations to help speed up specifically GetSelection and SetSelection below.
>Select All Text
>Find a matching format Using GetSelection, SetSelection
>>>Once I have a selection of items I check the format of the items this goes quite fast
>Work with regex of this text
When I do SetSelection all icons are updated, font combo etc. I am not sure if this is slowing things down. Thus my previous question.
Is there a way to have a TRichViewEdit SetSelection only select items and do nothing else no icon update, no showing of what is select just the bare minimum for speed. Or should I use something else than SetSelection (I need to work with items and offs) is there something in RVData that would be better?

Nevermind Sergey,
It was a problem with recopying over and over a large String. (I found my problem)

Just a note: ActionsEnabled disables all actions, but not font combo boxes. You need to assign Enabled properties of these combo boxes manually.
