TRzButtonEdit 8.0.1 Causes Error in Delphi 13.

[Steve Gill]

Hi Ray,

When I drop a TRzButtonEdit on a form in Delphi 13, I get an error.  I couldn’t attach a screenshot because your attachment requirements are too restrictive – the file is only 86KB and yet the forum still wouldn’t let me attached it.

So far this has only happened with that control, although I’ve only tried a couple of others, ie. TRzLabel and TRzEdit.

Yes, I see that too: ‘TRzButtonEdit  has no parent window…’

I get that error too.

Hi All,
I am able to duplicate the issue. Researching the issue now and will provide a fix to Embarcadero and/or a workaround as quickly as possible. I’ll keep this group posted.

Hi,
Very interesting bug. One little change from referencing Width to ClientWidth caused the issue. I have fixed the issue and submitted to Embarcadero. In the meantime before they can make a new version available, you can fix the issue by making the following two changes and then using the !Build_KSVC.cmd file (in the Source directory) to rebuild the components.

In RzBtnEdt.pas, update the beginning of TRzCustomButtonEdit.ResizeButtons to add the call to HandleAllocated:

procedure TRzCustomButtonEdit.ResizeButtons;
var
  W, MinHeight: Integer;
begin
  if HandleAllocated and not ( csLoading in ComponentState ) then
  begin

In the RzDbBnEd.pas, make the same edit to TRzDBCustomButtonEdit.ResizeButtons:

procedure TRzDBButtonEdit.ResizeButtons;
var
  W, MinHeight: Integer;
begin
  if HandleAllocated and not ( csLoading in ComponentState ) then
  begin

After making the changes, run the !Build_KSVC.cmd file and follow the instructions for rebuilding the runtime and design packages.

Is the problem just with the packages? I.e., if I’ve been using the component in my apps (no packages), are they OK? A quick test seems to indicate they are OK.

Hi David,
The issue is with the component itself and a change that was made in 8.0.1. I was able to duplicate the issue by dynamically creating the TRzButtonEdit. I’m kind of surprised there were not more reports of this problem, but if you are using 8.0.1 and not having an issue, there may be something else in play. In tracing through the code, the change from calling Width to ClientWidth resulted in low level VCL code being called that required a Window Handle to be allocated.

Hi Ray,

Will this fix, and any others, be in a 8.0.2 for Delphi 13.1??

[Steve Gill]

Hi Ray,

I’ve just circled back to this after finishing other projects I was working on.

I don’t seem to have RzBtnEdt.pas, or any other source code files for KSVC 8.0.1.

Never mind – I found it.  For some reason Agent Ransack couldn’t find it, but I found it manually.

[Steve Gill]

Hmm, I tried the fix but I’m still getting the error.  Has anyone else has any success with the fix?

[Ray Konopka]

The issue should be fixed in 8.0.2

[Steve Gill]

Thanks Ray!
