Juce and VST plugins

[cialz]

Hi to all,
I'm going to use Juce for developing some VST plugins.
In paricular I need to know if with this good library is possible to play an AVI video?

best regards

quicktime only I believe

[jules]

yes, but quicktime will happily play AVIs..

[cialz]

Oh, wonderful
Unfortunately at now I could not build Juce with VC++6
I've got two compiler error.

thanx

[Karbon L. Forms]

yes, but quicktime will happily play AVIs..

cool. didnt know that. tend to avoid QT like the plague.

[cialz]

So, I can show an AVI file in my VST plug GUI or only open QuickTime Stand Alone program?

[cialz]

It happens that the jucevst demo, after closing and opening sometimes the editor view, I can't see the gui, but only the 300x150 rect, without slider, string, and display.

Do you know why?

thanx

are you using the demo juce filter from the RMS site? IIRC it is somewhat buggy, but ost12666 has an improved version.

I'm using this

Why I need to clean up every time I have to build JUCEVST demo?
If I don't clean up, CL tells me the following errors:

Code: Select all

Compiling...

Hi, first of all I would ask you if it's right do this in the Editor Component constructor:

Code: Select all

openDirDialogButton->addActionListener ((ActionListener*)this);

I've used casting because the compiler notify me an error using "this" pointer

Then, I don't have understand how it works the event hander.

I think I have to concentrate around
- EditorComponent::changeListenerCallback(void *changedObject)
- EditorComponent::handleCommandMessage(int commandId)
- VSTplug::actionListenerCallback (const String& m)

Code: Select all

   //~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
void MultiVolver::actionListenerCallback (const String& m)
{
      if (m == "gain") setParameterAutomated(gain,(float)editorComp->slider->getValue());
      else if (m == openDirButtonName)
      {
         AlertWindow *aw = new AlertWindow(T("Titolo"),T("choose IR"),AlertWindow::InfoIcon);
         
      }
}


The alert window doesn't appear and also the tooltip when the mouse i over the TextButton

If you have to cast "this" to an actionlistener, then it clearly isn't one!

And I put lots of examples of how to use AlertWindows in the demo - have a look at that, or have a better look at the AlertWindow help docs.

AlertWindows are your friend! Well mine anyway. Absolute joy to use. 4/5 lines of code, on the stack, piff paff poof, user has given/seen his data, and it's done and gone.

Thanx Juce. I've inherited also from ActionListener the EditorComponet.

But why the tooltip message doesn't appear when I am over the TextButton?

Code: Select all

   //==============================================================================
        openIRButton = new TextButton (openIRButtonName,
                                     Colours::black,
                                     Colours::lightgrey,
                                     Colours::darkgrey,
                                     "click here to choose the Impulse Responses...");

        addAndMakeVisible (openIRButton);
        openIRButton->setBounds (10, 50, 100, 24);
        openIRButton->addActionListener (this);
        openIRButton->setTriggeredOnMouseDown (true); // because this button pops up a menu, this lets us
