Plug-in view content scale support: Vst::IPlugViewContentScaleSupport
- [plug impl]
- [extends IPlugView]
- [released: 3.6.6]
This interface communicates the content scale factor from the host to the plug-in view on systems where plug-ins cannot get this information directly like Microsoft Windows.
The host calls setContentScaleFactor directly after the plug-in view is attached and when the scale factor changes (system change or window moved to another screen with different scaling settings).
The host can call setContentScaleFactor in a different context, for example: scaling the plug-in editor for better readability.
When a plug-in handles this (by returning kResultTrue), it needs to scale the width and height of its view by the scale factor and inform the host via a IPlugFrame::resizeView(), the host will then call IPlugView::onSize().
