VST3 SDK 3.6.6: setMouseEnabled() – how to use it?

I like to set control B (AnimKnob) disabled if control A (OnOffButton) is set to ‘On’ (value 1.0f).

It works when I click control A.
It doesn’t work when
a) the plugin is loaded the first time
b) a preset is loaded
c) switching between generic editor – plugin editor (without changing a pramater value)

Code (VST3.6.6, VSTGUI4.3):

void ViewController::valueChanged(CControl* pControl)
float ctrlValue = pControl->getValue();
switch (pControl->getTag())
case kParamDriveMode:// control A
CControl* ct =getControlByTag(kParamDriveModeCoeff);// control B
if (ct) {
//ct->setVisible((ctrlValue == 1.0f));
ct->setMouseEnabled((ctrlValue == 1.0f));


In debug mode (VS 2015, Win 10) I can see that in any case the values are setting correctly.
But even when I set the background image or call setDirty(), invalid(), valueChanged(): it doesn’t work.

setVisible() instead of setMouseEnabled() works – but I don’t like to hide the control.

What do I miss?


VST3 SDK 3.6.5: VST2 wrapper & VSTGUI

Using the VST2 wrapper with VSTGUI 4.2.
It works for 64-bit VST2.

But the 32-bit VST2 plugin needs a refresh:
When I load another preset, the new data will be loaded (playing on the keyboard the new sound), but the GUI shows the old param values.
When I move the plugin window out of the screen & then back, the GUI is refreshed & shows the correct values.

This happens with plugin ‘note_expression_synth’ (SDK sample project).

If I use the new VSTGUI 4.3, the plugin shows an empty (white) window!
The same with the (new) SDK project ‘uidescription test’.
