Keyboard component

Component to allow you to get direct input from the keyboard. Specific keys can be polled to test if they are pressed and provide interaction with the runtime panel. A full list of virtual key codes can be found here: https://docs.microsoft.com/en-gb/windows/win32/inputdev/virtual-key-codes?redirectedfrom=MSDN

Examples

Here is an example of how to use the keyboard component to map key pressed to various functions on the panel.

FC6 Icon.png Keyboard Example


You can define keys that can be changed by the user by right clicking the keys in the keyboard component property and exposing them to the top level.

Once the properties have been exposed you can double click the top level property and rename to give a meaningful name in your application.

The user can then easily select which key they would like to assign to each function.
