text on a panel - on init

[Otto]

Hello,

I have a window with a panel and would like to show a text on the panel.
It is working when I use a button to start the action to fire the oPanel:say but I don’t find a way to show
the text when starting the program automatically.
Thanks in advance
Otto

Otto,

Why don't you create a SAY control as child of the panel ?

@ ..., ... SAY oSay PROMPT "test" OF oPanel

[Otto]

Hello Antonio,
Thank you for your response.
I need more than one line of text and many say – objects and pictures.
Then the application is overloaded and slow. It should become a kind of touchflow navigation.
Best regards,
Otto

Otto,

Then please try it this way:

oPanel:bPainted = { | hDC | oPanel:Say( ... ), ... }

When you want the panel to be repainted, simply do:

oPanel:Refresh()

Hello Antonio,
I made the changes you suggested but I can’t get it working.
Here is my code.
Thanks in advance

Otto,

My proposed code was fine but Class TPanel was not managing bPainted. So I have added Class TPanel at the bottom of the PRG and modified it properly.

This PRG is working fine:

Otto,

If you change this line, then you can see how it gets properly updated when you press "show" button:

oPanel1:bPainted = { | hDC | opanel1:Say( 195,169 , Time() , RGB(250,28,3) , , , .T., .T. ) }

Hello Antonio,

thank you so much. Perfect.
