#KEYUP ENTER CODE#
The keydown and keyup events provide a code indicating which key is pressed, while keypress indicates which character was entered. Modules Export and Import Dynamic Imports The keyup event is fired when a key is released.

ButtonBase considers KeyUp equivalent to a mouse left button down for purposes of raising a Click event. Property Flags and Descriptors Property Getters and Setters As an example, ButtonBase (the base class for Button) processes KeyUp so that it can check for the Spacebar or Enter key.

Switch Loops Functions Function Expressions Arrow Functions I confirm what you said: pressing Return close the MsgBox, but the Listbox also trap that Return and display another MsgBox as nauseam. The window have only the Listbox, and the two arrow keys works fine. Press ENTER to dismiss the popup - the popup will go, but then the KeyUp handler will be invoked again, and the message box will reappear, and so on, ad infinitum. I used this code (and nothing in KeyDown): When you run the app, press the ENTER key while the button has keyboard focus - the message box will pop up. What the Return True in MouseDown is meant to do ? You do not have a PushButton that have the Default behavior ? I do not understand how that can come. I have some things to do (right now), and I will make other testings in a brand new project (instead of a code addition to an existing project).ĮxpandRow: I would use these keys too (Enter AND Return). I understand the test part, but after your descripton, I do not understand.
