2 windows

t57042 · Post by **t57042** » Sun Oct 18, 2015 3:03 pm

Following code opens a window with 2 buttons. When clicking EXECUTE or pushing F5 a second window opens.
But only briefly! It Should remain visible until the same button is clicked again, which reopens and displays the second window over and over again.
What is wrong?

I cant really tell what you want the windows to do from your explanation, however:

SetActiveGadget(Editor_0) ; set focus on editor

brings the first window to the front, if you want the 2nd window to stay on top all the time, try using

StickyWindow(#Window, State)

or dont call SetActiveWindow right after the OpenWindow

Hi Richard. I've made the following modifications:

1. the SetActiveGadget(Editor_0) in the EXECUTE button event has been removed
2. it's not recommended for the main event loop to be in a procedure; moved out
3. Window_1 has been assigned to the second window with #PB_Any
4. the EXECUTE button event now determines whether to open the second window or just activate it if already opened
5. the screen-centered flag has been assigned to both windows

If the second window is closed manually, subsequent presses of the EXECUTE button would crash the program.

Hi TI
I posted what the man asked for (Close - Reopen)
In the matter of fact I do not like it that way
He should use Hide - Show and clear all the item for each new show
That will be much better

I'm sure you're right, Rashad.

Nonetheless, resetting the Run flag, whenever the window is closed manually, would easily remedy the error:

Code: Select all

Select event
  Case #PB_Event_CloseWindow 
    If EventWindow()=Window_0
      quit=1
      ProcedureReturn #False
    Else
      Run = 0
      CloseWindow(Window_1)
    EndIf
