Summary0001686: TJvLookout sets hintcolor black on black
Descriptionif you click on a button in the same outlookbarpage after two button press hintcolor is resetted to black (0) instead of clInfoBk.
If you change the outlook page everything is ok, but if you press more than one button on the same page hint is no more visible.
Additional InformationI've found a workaround, simply if you put the statement:
application.hintcolor := clInfoBk
in the Outlookbar.click event everything is fine
TagsNo tags attached.

I think the problem lies elsewhere because the proposed fix should *never* be necessary. I'll investigate further

Can you reproduce it if you drop a JvOutlookBar on an empty form? If not, the problem lies elsewhere.

Just to make it crystal clear: I can't reproduce your problem which to me indicates that the reason for black on black is caused by some other part of your code.

Peter,
I tried with a simple example and everything is fine.
The problem manifest itself in a complex application (btw the only one that I ported to Jvcl3). When compiled with JVCL 2 everything is fine, when I use version 3beta(9/4/2004) the problem arise as in my earlier description. Nothing else has changed. As soon as I can I'll try to nail down the problem with a small example.

There was a problem with black on black for hints originating in JvExForms.pas. I've attached the latest version to this issue. Try it and check if that's the cause of the error.

Peter,
I have uploaded a small sample (only two win with two components).
The problem seem to happen when clicking on the outlookbutton you call a modal dialog or window. Take a look at the sample, I have uploaded the exe too.
Simply click on button 1 or button 2 and check the hint color.
I try with your patch but I don't use JvExForms in my applications.

 Removing the "if not MouseOver" in TJvCustomLookOutButton.MouseEnter seems to solve it:

procedure TJvCustomLookOutButton.MouseEnter(Control: TControl);
begin
  if csDesigning in ComponentState then
    Exit;
// if not MouseOver then
// begin
    inherited MouseEnter(Control);
    if FFillColor = clNone then
      PaintFrame
    else
      Invalidate;
// end;
end;

Not sure why, though...

BTW, this is not in JvOutlookBar - this is in JvLookout. I'll change the subject

I think the correct implementations of MouseEnter and MouseLeave should look like this:

procedure TJvCustomLookOutButton.MouseEnter(Control: TControl);
begin
  if csDesigning in ComponentState then
    Exit;
  if not MouseOver then
  begin
    if FFillColor = clNone then
      PaintFrame
    else
      Invalidate;
  end;
  inherited MouseEnter(Control);
end;

procedure TJvCustomLookOutButton.MouseLeave(Control: TControl);
begin
  if MouseOver then
  begin
    if not FStayDown then
      Invalidate;
  end;
  inherited MouseLeave(Control);
end;

As it is now, the inherited call chain is interrupted and it risks getting out of sync. I'll update in in CVS

No reply, so assuming it works
