BlockUI

[Peter]

Hello,

if you want to block your UI (because you have a long running background process like HttpRequest or something else) you can use the $.blockUI() - Command (in JavaScript mode).

Here is a sample code how to use it:

Code: Select all

Enumeration
  #Window
  #Button
  #Timer
EndEnumeration

Procedure BlockUI(Message.s)
  ! $.blockUI({ message: v_message });
EndProcedure

Procedure UnblockUI()
  ! $.unblockUI();
EndProcedure

Procedure TimerEvent()
 
  UnblockUI()
 
  RemoveWindowTimer(#Window, #Timer) 
 
EndProcedure

Procedure ButtonEvent()
 
  BlockUI("<h1>Waiting 3 seconds...</h1>")
 
  AddWindowTimer(#Window, #Timer, 3000) ; Wait 3 Seconds...
 
  BindEvent(#PB_Event_Timer, @TimerEvent(), #Window)
 
EndProcedure

OpenWindow(#Window, 0, 0, 300, 100, "BlockUI example", #PB_Window_SystemMenu | #PB_Window_SizeGadget | #PB_Window_ScreenCentered)

ButtonGadget(#Button, 10, 10, 200, 30, "Block UI for 3 seconds")

BindGadgetEvent(#Button, @ButtonEvent())

Thanks very much for this great Tip, Peter! It's so easy and works like charme. I put a spinner using this code:

Code: Select all

BlockUI("<p><i class='fa fa-spinner fa-spin fa-4x' aria-hidden='true'></i></p>")

The spinner is shown, but any idea how I can remove the white box in the background? Would like to show just the spinner itself.
