Wrapper Example (ActiveQt)

ActiveX controls in this example are the standard button classes QPushButton, QCheckBox and QRadioButton as provided by Qt.

The factory implementation returns the list of supported controls, creates controls on request and provides information about the unique IDs of the COM classes and interfaces for each control.

QAXFACTORY_EXPORT( ActiveQtFactory, "{3B756301-0075-4E40-8BE8-5A81DE2426B7}", "{AB068077-4924-406a-BBAF-42D91C8727DD}" )

The factory is exported using the QAXFACTORY_EXPORT macro.

To build the example you must first build the QAxServer library. Then run qmake and your make tool in examples/activeqt/wrapper.

The demonstration requires a web browser that supports ActiveX controls, and scripting to be enabled.

<SCRIPT LANGUAGE="VBScript">
Sub ToolButton_Clicked()
    RadioButton.text = InputBox( "Enter something", "Wrapper Demo" )
End Sub

Sub PushButton_clicked()
    MsgBox( "Thank you!" )
End Sub

Sub CheckBox_toggled( state )
    if state = 0 then
        CheckBox.text = "Check me!"
    else
        CheckBox.text = "Uncheck me!"
    end if
End Sub
