Appdeveloper: use a short key?

[stefan.erni]

Hi Steve

Is it possible to have a shortcut key for an existing switch in Appdeveloper?
For example, “space” to start recording.

Hi Stefan,

For PC developer you can use Key Mappings available from the Edit menu.

You can assign a calculation to a keypress, for example I have this to toggle a variable on and off when the S key is pressed.

You can monitor for this variable changing by having a decision in your main loop checking if the variable is equal to the old value.

It works fine for the PC developer source and for the export.

If you want this for web developer then let us know and we can see what's possible.

Hi Ben

Perfect!

I add key mapping and use the switch with call macro if click (OnButtonClick). This works very well.
Only the switch doesn't have such a good 3D effect.

short key and switch works nice together.

Hi Ben

One more question:
Does the keymap only work in the main part from the APP?
It doesn't work in a macro.

It looks like you need to have the Simulation Speed (in the Simulation Debugger window) set to "Fast (with updates)".

This is part of Flowcode that has not been looked at in a very long time, so I will add it to our list to investigate and see if we can have this working better.

Hi Steve

Ok in the simulation it's working, if I set max speed and stepp in macros.

But in the exported APP, it's only working in the main and not in the macro.

The good thing is:
In the exported APP, the keys works in the main perfect!
