I'm developing an audio plugin based on the Redwood example using Xcode on Mac, and I'm using Steinberg VST3 Plugin Host to test the plugin.
The plugin is resizable using custom code, but I am not able to resize the plugin by trying to resize the VST3 host. When mouse cursor goes over to the edge of the plugin the cursor changes to a "resize" cursor, then I try to resize the host by dragging it but it never resizes.
The only way I can resize the plugin at the moment is having a magnifying glass icon hooked up to mouse events for resizing on the plugin.
My questions here are:
1) If it's possible to let the VST3 host or any other hosts to respond to the mouse dragging for resizing and then notify the plugin.
2) If above is not possible, is it possible not to change the mouse cursor to a "resize" cursor when it goes over to the edge of the plugin?
