Hia peeps,

Okay, so my VST plug-in works fine, but now it's time to make it looks snazzy.
The plug-in is coded in XCode (using VST2.4 sdk), and I'm trying to use VST GUI 4 to implement my custom view. The VST SDK has a "getting started" section as well as an XCode tutorial project that I followed very closely to build up just a basic view to start off with. But this is what I'm getting (after building the plug-in and bringing it up in Audacity for the first time):


If I close Audacity, open it up and bring up the plug-in again, I get a gigantic, blank window that takes up half my screen; and this is within the same build of the plug-in -- no code is changed, just reopening the host and selecting the plug-in. When I get the small window with the knobs under the buttons, I can move them around and it works as expected, but something is completely off with the view obviously.

It seems the window isn't scaling to the view size I specify with CFrame. I've racked my brain over this and can't see what I'm doing wrong. Anyone have any insight into this? It seems like such a basic thing to get VST GUI up and running with a simple view, but I just can't get it working properly. Maybe I'm missing an important Framework (the tutorial has Accelerate, Carbon, Cocoa), or build setting, ...?

Inside my plug-in constructor I have:

// set editor for plug-in GUI
   extern AEffGUIEditor* createEditor (AudioEffectX*);
   setEditor (createEditor (this));

Then, inside the editor .cpp file:

AEffGUIEditor* createEditor (AudioEffectX* effect)
{
   return new RingModEditor (effect);
}

//--------------------------------//

RingModEditor::RingModEditor (void* ptr) : AEffGUIEditor (ptr)
{
}

//--------------------------------//

bool RingModEditor::open (void* ptr)
{
   CRect frameSize (0, 0, 300, 300);
   CFrame* newFrame = new CFrame (frameSize, ptr, this);
   newFrame->setBackgroundColor(kWhiteCColor);
    ...
    // additional code setting up knobs, etc.

//--------------------------------//

void RingModEditor::close ()
{
   CFrame* oldFrame = frame;
   frame = 0;
   oldFrame->forget();
}



Along the same lines, what's the opinion on VST gui? Are there better tools out there for custom UI? What do you guys use for custom UI? I read a little bit about JUCE and it seems pretty cool.

Much appreciated.

You need to implement the getRect() method in your editor, as follows:

virtual bool RingModEditor::getRect(ERect** rect);

This is where you specify the size of the window the host will open for you.

'Tick

Magic!
Thank you, sir.

In case others encounter this problem, I added these lines of code inside the 'open' function of my plugin editor:

ERect *wSize;
getRect (&wSize);
wSize->top = wSize->left = 0;
wSize->bottom = wSize->right = 300;


And then you go about creating the view frame, attaching it to the parent window, etc.
