Event when frame change size

[artem_niko]

Hello!

I need execute somebody event when frame change own size.

For example.

I have a UniForm and frame. This is frame creating in this UniForm. And when UniForm change own size, frame also change own size and at this moment I want run my event, for example, ShowMessage('ololo');

Event must be executing only when frame change own size, not UniForm.

Is it possible make?

Do you know about event of form as know as Maximize? If not use UniGUI and use standart Win32 project on VCL.

I need analog of this event. When form maximize - frame also change own size and on this moment I must show message.

Maybe you want this event?

YourForm.ClientEvents.ExtEvents ->

function window.maximize(sender, eOpts)
{
    
}

Hm...Maybe...

And what about Frame?

Is it event 

YourFrame.ClientEvents.ExtEvents ->

function resize(sender, width, height, oldWidth, oldHeight, eOpts)
{

}

Is analog of event form?

YourForm.ClientEvents.ExtEvents ->

function window.maximize(sender, eOpts)
{
    
}

Well, as you know, these two events are different in the sense that resize event is always executed when resizing ...
And the frame does not have the "maximize" event.

What exactly you want to do?

For resizing the Frame the best solution is layout.

i use this WorkAround:

 

Please set a uniImage in the background of your frame (without Picture - just the uniImage)

set all Anchors ..

 

and test following code:

procedure TyourFrameName.UniImage1Resize(Sender: TUniControl; OldWidth,
  OldHeight: Integer);
begin
 a_test_uniLabel.Caption:=inttostr(UniImage1.Width) +' - '+ inttostr(UniImage1.Height)
end;

 

if you resize your frame OR the Webbrowser - you will get the event ... and if your image is Aligne: alClient - you will get the Width and Height of your frame

 

 

Hope this helps :-)
