Best way to destruct UI panels?
-
So I have an init script that reads the number of installed expansions and creates a panel for each one that it finds. However I currently have to manually delete them before exporting the vsti (so that the plugin starts with 0 as the user won't have any expansions until they install them).
Is there a good way to destruct these automatically on plugin close, or before exporting?
-
@iamlamprey you can also try to hide them when opening with a button that closes them? If I understood correctly . button.showControl (value); you set the default button to 0 and when opening the panels will be hidden. sorry if i misunderstood but just in case ... :)

Use this approach for dynamic content, your solution of creating static panels at onInit is messy.

@yall I've already got a button to open/close them :) the issue is it's still drawing blank/empty panels before the user has any expansions loaded
@Christoph-Hart Thank you! I'll get to reading
-
It's so beautiful

@Tania-Ghosh weird, it's just a short video of the UI working properly :)
-
@iamlamprey it seems to work fine right? can you publish the snippet of your project? normally in the expansion example there is not this problem of panels
-
I do it with a single panel + paint routine + mouse callback. What's the advantage of multiple panels in this use case?
-
@iamlamprey hmm.. I know. I always love to see what everyone is doing. It gives me the potential to learn HISE properly.

@yall I can post a section of my frankenstein code
/* First we create a Viewport so we have access to a scroll bar (we can do this with scripting but I just drew it in) Then we add a big "master panel" inside the viewport that we'll fill with all of our buttons. Any changes we make to the Viewport will also apply to the child components (such as hiding) */ const var Panel_ExpansionsItemHolder = Content.getComponent("Panel_ExpansionsItemHolder"); const var expHandler = Engine.createExpansionHandler(); //Grabs the names of each expansion as a string and pushes them to an array. const var expansionNames = []; expansionNames.push("No Expansion"); for (e in expHandler.getExpansionList()) expansionNames.push(e.getProperties().Name); //Populate List const var expButton = []; //I used an array to store a "button" for each expansion, you could probably do one giant panel with XY coordinates. const var expButtonHeight = 55; //The height of a single Library Button //We'll make use of the Panel.addChildPanel(); function to populate our list. //"Libraries" Title at the top of the list (not a button) const var expPanelTitle = Panel_ExpansionsItemHolder.addChildPanel(); expPanelTitle.setPosition(0, 0, Panel_ExpansionsItemHolder.getWidth(), 20); expPanelTitle.setPaintRoutine(function(g) { g.fillAll(0x1B1B1B); g.setFont("Arial", 12.0); g.setColour(Colours.white); g.drawAlignedText("- Libraries -", [0,0,Panel_ExpansionsItemHolder.getWidth(),20], "centred"); }); /* Crawling the expansion list and populating with buttons + images. Note that these images are filmstrips so this has mouseover/click down animations. They also call custom functions on click down, which I won't put here. Basically these custom functions handle all the expansion-loading, image-swapping and sampler-setting-uppering. */ for (i=1; i<expansionNames.length; i++) //We start at 1 because 0 is "No Expansion" { Panel_ExpansionsItemHolder.set("height", 20 + expansionNames.length * expButtonHeight - 55); expButton[i] = Panel_ExpansionsItemHolder.addChildPanel(); expButton[i].setPosition(0, 20 + i * expButtonHeight - 55, Panel_ExpansionsItemHolder.getWidth(), expButtonHeight); expButton[i].loadImage("{PROJECT_FOLDER}" + expansionNames[i] + "_button_base.png", "panel_" + expansionNames[i]); //Appends a bunch of strings to return the full file name. expButton[i].data.imagefile = "panel_" + expansionNames[i]; expButton[i].data.expansionName = expansionNames[i]; expButton[i].set("allowCallbacks", "Clicks & Hover"); expButton[i].setPaintRoutine(function(g) { g.drawImage(this.data.imagefile, [2, 1, 185, 55], 0, 0); //My panels were 185 wide, you could use getWidth() but I got lazy :P }); expButton[i].setMouseCallback(function(event) { if (event.clicked) { expHandler.setCurrentExpansion(this.data.expansionName); load+this.data.expansionName; //This is our custom function loadSomething(); this.setPaintRoutine(function(g) { g.drawImage(this.data.imagefile, [2, 1, 185, 55], 0, 110); //Offsetting the filmstrip to the click-down animation }); } else if (event.mouseUp) this.setPaintRoutine(function(g) { g.drawImage(this.data.imagefile, [2, 1, 185, 55], 0, 0); }); else if (event.hover) this.setPaintRoutine(function(g) { g.drawImage(this.data.imagefile, [2, 1, 185, 55], 0, 220); //Offsetting the filmstrip to the hover animation }); else this.setPaintRoutine(function(g) { g.drawImage(this.data.imagefile, [2, 1, 185, 55], 0, 0); }); }); }; /*It's probably not the most efficient or performance-considerative, but it works for now. I should also probably add set("isMomentary") to the "buttons" so they don't wig out, as well as remove "storeInPreset". I'm also hiding this whole viewport with a simple button that sets Viewport.showControl(value) and offsets the main GUI panel by 180 or whatever*/

@d-healey I'm using image files, it could probably still be done in a single panel using some cursor XY trickery but this is easier for my noob brain to wrap around :face_savoring_food:
-
@iamlamprey said in Best way to destruct UI panels?:
@d-healey I'm using image files
Me too, downloaded from a server
-
@d-healey And that's all a single panel and you're using some XY position detection thing in your callback? Fancy
-
@iamlamprey It's not really anything fancy
Panel1.setMouseCallback(function(event) { var x = Math.floor(event.x / this.getWidth() * this.data.cols); var y = Math.floor(event.y / this.getHeight() * this.data.items.length / this.data.cols); var v = x + y * this.data.cols; if (event.clicked) { this.setValue(v); this.changed(); } });
-
@d-healey Nice! What is this.data.cols?
Then just do stuff when value = 1?

Here's full example.

@d-healey You could even make those squares link to your patreon :winking_face:

@iamlamprey Christoph showed me this technique in one of my livestreams (I think it was the second one).

@d-healey Livestream! Yeah... I like that idea! It's been a while, hasn't it?
