Computer keyboard input

Can we detect any QUERTY keyboard button presses in HISE? I'm thinking mainly of modifier keys like CTRL, SHIFT, and ALT.

Christoph Hart

You mean in combination with mouse clicks?

The thing is that modifiers alone don't trigger any callback in JUCE, so you need either another keypress or a mouse event.

What do you want to achieve?

d.healey

Yes it would be with a mouse click. So when a control is clicked you could check to see if a key is also held. I use this kind of thing for example if I want a single button to have more than one purpose. Or a recent project I worked on a user could enable multiple articulations by selecting more than one button, they hold CTRL down if they want to select more than one otherwise it just selects one.

Christoph Hart

This is a reasonable request. You'll need to roll your own widget from a Panel then, because the other widgets have already some hardcoded modifiers (eg. dragging sliders with Ctrl enables fine tune mode)

d.healey

I think I'm getting the hang of the panel now so that shouldn't be an issue

Christoph Hart

Alright, I added the modifier keys:

event.isShiftDown
event.isAltDown
event.isCmdDown
event.itCtrlDown

BTW, if you call setValue() with a Panel, the controlCallback isn't executed automatically (to prevent recursive loops). You need to call Panel.changed() to execute the control callback.

That was quick! just trying out the new build now.

Hi guys,

I'm trying to make it work but it still doens't work using a panel.

Here's a snippet:

Any ideas?
Thanks again for the help!

@d-healey

Thanks a lot, It works!

Simon

I'll bring this topic back from the grave and ask the compliment of David's question. Is it possible to get normal keypresses? Specifically, letters A-Z, maybe characters too.

d.healey

@Zorpley https://docs.hise.audio/scripting/scripting-api/content/index.html#setkeypresscallback

Simon

@d-healey As usual I found it right after asking. Thanks David!

Simon

To implement keyboard playing like you find in DAWs, might there be a way to get the current keyboard layout as well? I'll specify that I want to use the (PC) keyboard to set the current chord in a plugin, not play a MIDI note directly.

Not that I'm aware of, but you could setup some predefined ones and let the user pick.
