Cursor not showing when TSRichViewEdit is in a VCL Frame

If I place a TSRichViewEdit in a frame, the cursor is not shown. When I place the same TSRichViewEdit directly in the form that contains the frame, the cursor is visible (and blinking). Using Delphi 10.3 Rio and ScaleRichView-Pre9.

I confirm the problem.
Quick fix: open <TRichView Dir>\ScaleRichView\Source\SclRView.pas, add to the end of the procedure TSRichViewEdit.CreateWnd:
Code: Select all
if srvs_TimerCaret in FState then
UpdateCaretTimer;

Hi!
I recently updated my version of ScaleRichView. I find this same problem: Cursor not showing when TSRichViewEdit is in a VCL Frame.
The same form (with a frame with a ScaleRichView) was working well until the update. The only problem that I have detected so far is that the cursor does not to blink.
Within TSRichViewEdit.WndProc(), execution enters into the second IF only once, at first. Is that data useful?
In SclRView.pas
Code: Select all
procedure TSRichViewEdit.WndProc(var Message: TMessage);
begin
inherited;
if IsNotRunTimeMode then
exit;
if not(srvs_TimerCaret in FState) and HandleAllocated then
begin
Include(FState, srvs_TimerCaret);
FPageProperty.PageWidth := FPageProperty.PageWidth;
FPageProperty.PageHeight := FPageProperty.PageHeight;
UpdateView;
UpdateCaretTimer;
OldPageCount := 0;
CalculatePageCount;
end;
end;
Thanks for readme

Hello Sergey, thanks for answering.
I had not done it because-this post being so old-I thought it was already incorporated into the library.
I just did it and it works perfect!
Thank you!

Hi, last week I upgraded TSRichViewEdit to the latest version. I found out that this issue is not fixed in the latest release. Is there a specific reason why this fix is not included?

Because there were no updates yet. The next update is almost ready, it will be released in this week.
