Hi

I’m trying to develop a VST plugin GUI by using SDL (Linux initially). In VST 2.x plugin interface, the plugin gets already created window handle it should start using it so I’m looking for a CreateWindowWithHandle(window\_handle) function but there is only CreateWindowFrom(void \*ptr) and giving window handle (from DAW call) to this function seem to lead to crash/is not working. (the window\_handle is an Xlib Window (or an xcb\_window\_t).)

This page shows how plugins are called (effEditOpen command is send to plugin):

[https://github.com/ekenberg/vstminihost/blob/master/source/minieditor.cpp](https://github.com/ekenberg/vstminihost/blob/master/source/minieditor.cpp)

Do you have any suggestions what I should do?
