Question about UI Json data!

d.healey

Floating tile keyboard doesn't appear to be working. I've added a floating tile and I'm using this code

const var fltKeyboard = Content.getComponent("fltKeyboard");
fltKeyboard.setContentData({"Type":"Keyboard", "LayoutData":{}, "LowKey":24});

but it's just showing up as a blank panel

Something else that's strange, I have 3 controls on my GUI - all added through the point and click method, but only one is showing up in the UI JSON. The two that arne't showing up are child components of the one that is there if that makes a difference?

Update: I got the keyboard to show up by making it not a child component (still doesn't show in the JSON though) is this intentional behaviour?

Christoph Hart

Ah, now I understand what's the problem. Just forget about the UI JSON Data that can be shown in the code editor, I'll remove this soon in order to avoid this confusion in the future. This is a misfortunate attempt to expose the raw data to the user but doesn't work at all with nested components, breaks up the connection between the data model and the interface and does all kinds of other stupid things. Actually I forgot it's there (I implemented it at the beginning of the redesign and forgot about it later on).

In a normal scenario you should not need to access this data directly, and if you do it, the JSON popup editor is the way to go (it's still not ideal because you loose every undo history, but as last resort OK).

d.healey

Aha that explains 99% of my confusion :)

A few more things I noticed:
When opening a .hip each module is folded up now, could we have a context menu for each module to unfold/fold it?
Holding Alt while dragging the currently selected control on the canvas doesn't appear to duplicate it.
Ctrl+Z doesn't undo a canvas action - Linux strikes again I think because CTRL+SHIFT+Z works
Copying properties from a control and pasting them onto another worked great, but then I created another control and hit paste again (didn't copy again), result was that HISE instantly closed.

Is the best way to add controls in a loop still to use Content.addControl();?

Christoph Hart

Oops, you're right, something broke the restoring of the fold states. I'll investigate.

Have you tried the "Windows" key for duplicating? (I assume you're still using a Windows keyboard on Linux)? Sometimes the modifier keys get a bit confused.

However I need to go into Linux now anyway because I migrated to JUCE 5, then I'll check that everything works there as expected.

d.healey

I just tried the Windows key but no luck there

Christoph Hart

I am currently compiling the Linux version of HISE, then I'll check what's the key there :)

Christoph Hart

Ah now I see, these keys somehow interrupt the dragging operation because they do some OS specific functions. That's too bad, not sure how to fix this and the only working modifiers (Shift / Ctrl are already used).

Christoph Hart

Solved it. Just press Ctrl+D and it will duplicate the selection to the current position. No need to hack around the modifier keys...

Funny story: this is nothing new, but I forgot about it because the shortcut was broke like the rest...

Christoph Hart

Hey David, can you check the latest version on Linux (it's on the juce_5_migration branch? HISE crashes when loading the simplest project, but I suspect it is something stupid going on in my VirtualBox.

d.healey

I'll build it now

Christoph Hart

It seems to crash at a memory copy operation which might be caused by some missing SSE flags that the virtual box can't set because it has to add a CPU emulation layer (long shot, I know).

d.healey

Well I tried opening an existing project and instant crash.

So I created a new project, saved a blank preset, closed and reopened, loaded the preset and no crash.

I then added a sampler with a single sample, closed and reloaded, no crash.

I then added a script to the master container, the only line I put in the script is Content.makeFrontInterface(500, 200);. I closed and reloaded and instant crash.

Christoph Hart

Hmm, I can't even load a preset with a single sine wave oscillator without a crash.

I'll ask the JUCE guys what could be wrong there.

d.healey

I just tried a project with a single sine oscillator and it crashes for me too.

Slider.setPropertiesFromJSON(); is giving me a function not found error

Christoph Hart

It is and had always been Content.setPropertiesFromJSON("Slider", object) :)

d.healey

Aha, the API needs updating, it shows ScriptSlider.setPropertiesFromJSON( var jsonData)

Using Content.setPropertiesFromJSON() doesn't produce an error but it doesn't seem to have any effect on the controls and they no longer show the property overridden by script message, which was displayed when using Slider.set()

Christoph Hart

Hmm,

Add a knob called Knob1.
Add this line: Content.setPropertiesFromJSON("Knob1", {"width": 200});
The Knob should get wider and the property is deactivated (even on Linux).

d.healey

You're right! I was using the variable of the component instead of using the component ID. Solved :)

Christoph Hart

I am using the ID instead of the variable almost every time I need to pass in an control as parameter to a function (and I would heavily recommend this paradigm for your own functions). The reason is to avoid reference counting cycles:

// If you would pass the variable instead of the ID:
CloseButton.set("parentComponent", parentAsVariable);

// and later for some weird reason:
parentAsVariable.data.closeButton = CloseButton;

// BOOM, Cycling reference & leaking

BTW, the Linux crash is fixed now :)
