WebViewGadget: SetGadgetText is not displaying content

Hello everyone,
maybe a stupid question: Why isn't purebasic.com displayed, after pressing the button?
This is just a demo code:
Code: Select all
If OpenWindow(0, 200, 200, 800, 840, "")
ButtonGadget(0, 0, 0, 200, 40, "Press")
WebViewGadget(1, 0, 40, 800, 800)
SetGadgetText(1, "http://www.google.com")
EndIf
Repeat
event=WaitWindowEvent()
Select event
Case #PB_Event_Gadget
Select EventGadget()
Case 0
Debug "ok"
SetGadgetText(1, "https://www.purebasic.com/") : Delay(5000)
Debug "ok"
SetGadgetText(1, "http://www.w3schools.com")
EndSelect
EndSelect
Until Event=#PB_Event_CloseWindow

Never block the event loop -> Delay(5000)

Delay is just instead of a procedure to demonstrate. I do have problems doing this (without delay).
Another demo:
Code: Select all
Procedure test()
For i=1 To 200000000
Next
EndProcedure
If OpenWindow(0, 200, 200, 800, 840, "")
ButtonGadget(0, 0, 0, 200, 40, "Press")
WebViewGadget(1, 0, 40, 800, 800)
SetGadgetText(1, "http://www.google.at")
EndIf
Repeat
event=WaitWindowEvent()
Select event
Case #PB_Event_Gadget
Select EventGadget()
Case 0
Debug "ok"
SetGadgetText(1, "https://www.purebasic.com/") : test()
Debug "ok"
SetGadgetText(1, "http://www.w3schools.com")
EndSelect
EndSelect
Until Event=#PB_Event_CloseWindow
I thought:
1) purebasic will be displayed
2) test() will be called
3) w3schools will be displayed
Not? How to do that? Thread?

Exactly the same as with Delay.
The events must be processed. Otherwise the WebViewGadget will not be updated.
It is not possible from Thread, as the events must also be processed.
However, this is not a problem, as the WebView internally processes everything in Thread in the background anyway.

Hmmm ... thx!
The strange thing with the code I'm using: The
first one will be displayed and the second one not ...
I thought, I could demostrate the issue with the code above, but your explanation sounds plausible.

You can do it with a timer for a demo.
