I have a popup window that serves as a loading window. It consists of a background image and a small image that contains an ajax spinner gif. If I click on this loading window too many times the ajax spinner stops animating. If I click once more Windows displays, "App is not responding".
Is there a way to disable all input so that this does not happen? I tried putting an empty super control over the top of the entire window, but this only seems to give me a few extra clicks. This window is displayed via threading code below.
PROCEDURE DisplayLoadingWindow() ThreadExecute("ThreadLoadingWindow", threadNormal, ExecuteLoadingWindow) ThreadWaitSignal()
PROCEDURE ExecuteLoadingWindow() // Show Window OpenChild(WIN_Popup_Loading) // Wait for Signal ThreadSendSignal(threadMain) EventWait("CloseLoadingWindow") // Close Window Close(WIN_Popup_Loading) // End Thread ThreadEnd()
PROCEDURE CloseLoadingWindow() EventChange("CloseLoadingWindow", eventOpen) |

Hi Curtis,
there is a good chance that the problem is coming from you ignoring the FIRST and MOST IMPORTANT rules of using threads: do NOT access the UI from a secondary thread, EVER.
And of course, opening a window from a secondary thread is smack in the middle of that one.
Any action on the UI from a secondary thread must be done through one of the 3 (from memory) workarounds described in the threads help.
Best regards |
