[Solved] TPopupMenu does't seem to work for TComboBox?
« on: March 11, 2011, 09:35:12 pm »
TPopupMenu does't seem to work for TComboBox?  Is this by design, or do I have something set wrong?

Works here (Qt) - when Combo is closed. Does't work if combo is opened, in this case right-click only selects item. I think it is normal.

Mmm.  I must have something set wrong someplace though I can't think where.  I just added the first popup so there is no code that I can think of that would cause this.  Popup works fine in TEdit, but in TComboBox.Text area it gives the standard popup as though no popup was assigned.  Same for the ComboBox Items List.  I'm using Win7-64 and FPC 2.5.1 if that means anything.

OK.  I started a new blank program to test the problem with the Popup Menu.  I added a TComboBox, a TEdit and a TPopupMenu. The PopupMenu acted as expected on the TEdit, but on the TComboBox I got the default popup menu, Not the menu I provided.  So it appears that the problem isn't with my code.  It isn't that big of a problem for me.  I can find another way to do what I need to do.  But if this is a bug in FPC or Lazarus, it should be addressed.  Then again, maybe I'm just having a bad day.

I can reproduce too. But i think it's a normal behavior.

Lazarus 0.9.31 r29668 FPC 2.4.3 i386-win32-win32/win64


Look at the picture ;)

Ah, I see.  Thanks FabienWang :)  I didn't know that.  I was expecting it to act the way it does in Delphi.  I'm not sure yet which way I like better.  I'll have to give it some thought, although I don't think it matters.  If this is Lazarus way, then that's the way it will be.  I'm very new to Lazarus but an old-timer with Delphi.  So far, I'm loving what I see with Lazarus.

Great :) same for me about Lazarus :)

oh and as you said, if you'd really want your popup menu,
you can still implement the onMouseDown of the combobox,
and put:

  if Button = mbRight then
    PopupMenu1.PopUp;

it will work ^^

PS: you can change the first post topic with "[SOLVED]" or something :)

Best Regards,
FabienWang

Is it not a bug? Should we do it in onMouseDown?
