I am not getting a simple mouseup event?

Is there a reason why I am not getting a simple mouseup event? If I do the same for a mousedown event it works. see pic link

Hi Louis, in order for mouse up to trigger you have to Return True in the mouse down event.

Hi Steve
A beginner stuck in VB.
That worked.
Thank you
Lou

You know, there’s a number of great resources for beginners.

There’s a manual that comes with Xojo that teaches you the ins and outs of using the IDE, the language, and the features within. You can find that in the Documentation folder next to your installation of Xojo. There’s also an online reference http://documentation.xojo.com

And when you’re ready to learn from examples, there’s a folder full of example projects next to your Xojo install called “Example Projects” It helps when you don’t intend to reinvent the wheel.

Best of luck :slight_smile:

I am also struggling with this. When place “Return True” in the mouse down event, the event is cancelled. For example, I cannot resize columns in a listbox if “Return True” is in the mouse down event.

So you need to reconsider what you are doing with mouseup.
What are you wanting to do when the mouse goes up?

FWIW, a solution to the actual issue was posted in the thread that was bumped just four hours ago.
It’s just not a copy/paste code example.
