Block mouse click

[stina]

How can I block or ignore a mouse click and other events? When data is processed I change the cursor to the hour glass and then I don't want the user to be able to push any buttons.

To block user interface events from being generated, you must discard the corresponding events in the controls callbacks.

In your application, you can use a global variable as a flag for "updating in process" and in controls' callbacks swallow the user interface events, this way:


if (operationInProgress) {
switch (event) {
case EVENT_LEFT_CLICK:
case EVENT_RIGHT_CLICK:
case EVENT_LEFT_DOUBLE_CLICK:
case EVENT_RIGHT_DOUBLE_CLICK:
case EVENT_KEYPRESS:
return 1; // Swallow the events
default:
return 0;
}
}
