ActiveX Control Grayed Out

[AppAnoAndre]

When I add a QAxWidget in Qt Creator and then I select "Set Control", some ActiveX controls are grayed out. Including the one I want to use.

I know this control works because I use it on this machine with different apps. What is Qt Creator unhappy about?

Thanks!

Hi, (I'm assuming you're running MSVC on Qt 6.4,2)
Perhaps you're trying to instantiate a 32-bit control? For example, if I create an QaxWidget in Qt Creator, right click it and selects :"Set control" and then type "Adobe" in the filter:

the 64-bit versions of the ActiveX controls are ok:

but the 32-bit versions are greyed out.

Note the filename that is ok is AcroPDF64.dlll but the filename that is not ok (greyed out) is AcroPDF.dll

Unfortunately, ActiveX controls are not supported in Qt. You may be able to use a third-party library to achieve this, but it is not something that is supported natively.

Wrong. https://doc.qt.io/qt-6/qt-activex.html
