Removing Selection

palmeira · Post by **palmeira** » Fri Feb 13, 2009 11:07 pm

If I select some text (or an entire document) and click in part of the selection, sometimes the selection is removed, but more often it is not. Is there a way to make the selection always be removed?

Edit: I also use a component TRVAPopupMenu with live spell checking. If I right click a mispelled word, it does no display the suggestions provided by the spell checker. In order to make it work correctly, I have added the following code to the OnMouseDown event:

if Button = mbright then
if ve1.GetSelText = '' then
begin
{Simulate mouse move}
Mouse_Event(MOUSEEVENTF_ABSOLUTE or MOUSEEVENTF_LEFTDOWN, x, y, 0, 0);
{Simulate the left mouse button up}
Mouse_Event(MOUSEEVENTF_ABSOLUTE or MOUSEEVENTF_LEFTUP, x, y, 0, 0);
end;

What version SRV do you use?

As for spell checking.
You need to call this code:

Code: Select all

  RVA_GetRichViewEditFromPopupComponent :=
   SRVGetRichViewEditFromPopupComponent;

one time when the application starts, for example in the initialization section of the main form unit.

Thanks for the posts.

1) I am using ScaleRichView version 2.0.3.

2) I had already added the popup code. The popup is shown when I right click a word, the problem is that the correction suggestions are not (unless I simulate a left click, as mentioned.) Anyway, I reported this just for your information, as I already have a work-around.

In ScaleRichView version 2.0.3 were problems with selection. Load ScaleRichView version 2.0.4.

I have just installed version 2.0.4, but it has not solved the problem.

Is the problem with selection persistent? I.e. if you repeat the same actions again, the result is the same? If yes, please give the step-by-step instuction how to select text and then click so that the selection is not cleared.

Sometimes the selection is cleared, sometimes it is not. I have the same problem with the rvaction demo (with scalerichview), but I am not sure e-mailing the source or the executable would be any help, as I have not changed the source.

I have, however, applied the patch to RVECaretMove:

procedure TSclRVRuler.RVECaretMove(Sender: TObject);
var
RemCanUpdate : Boolean;
begin
if not FSRichViewEdit.CanUpdateMargin then
Exit;
UpdateRulerIndents;
UpdateTableEditor;
if PageCurrent <> FSRichViewEdit.CurrentPage then
begin
RemCanUpdate := FSRichViewEdit.CanUpdate;
if RemCanUpdate then
FSRichViewEdit.CanUpdate := FALSE;
Scrolled;
UpdateTableEditor;
if RemCanUpdate <> FSRichViewEdit.CanUpdate then
FSRichViewEdit.CanUpdate := RemCanUpdate;
end;

if Assigned(FRVECaretMove) then
FRVECaretMove(Sender);
end;

I will check it tomorrow it that is what is causing the selection not to be cleared.

I reverted to the original code, but it made no difference: when I click inside a selection, most often the selection is not cleared, as before.

You can send me example EXE of a file in which there is an error? I cannot reproduce a problem with selection.

The files have been sent

I have looked. This bug has already been fixed. You downloaded SRV the version v2.0.4? In the new version this bug has been fixed. I have sent you the corrected version. Soon we will download updating.
