/*! @class VST3Editor
The VST3Editor class represents the view for a VST3 plug-in. It automatically binds the VST3 parameters to VSTGUI control tags and it includes an inline UI editor for rapid development.
@section setup Setup
Add the following code to your Steinberg::Vst::EditController class:
@code
IPlugView* PLUGIN_API MyEditController::createView (FIDString name)
{
if (strcmp (name, ViewType::kEditor) == 0)
{
return new VST3Editor (this, "view", "myEditor.uidesc");
}
return 0;
}
@endcode
To activate the inline editor you need to define the preprocessor definition "VSTGUI_LIVE_EDITING=1".
Rebuild your plug-in, start your prefered host, instanciate your plug-in, open the context menu inside your editor and choose "Enable Editing".
Now you can define tags, colors, fonts, bitmaps and add views to your editor.
See @ref page_uidescription_editor @n
