[ActiveQt] How can I get IDispatch pointer from QAxObject?

Hello.

I'm using MapWinGIS ActiveX control.
I want to add a shp file layer to map control, and map control needs IDispatch pointer.
Shpfile is a QAxObject class. (created by dumpcpp tool.)

Code:

---

#include "MainWindow.h"
 
using namespace MapWinGIS;
 
MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent)
{
	QString mapPath = "ne_10m_admin_0_boundary_lines_land.shp";
 
	ui.setupUi(this);
 
	ui.map->SetBackColor( Qt::black);
	Shapefile *sf = new Shapefile();
	sf->Open( mapPath, NULL );
 
	ui.map->AddLayer( ????? );
}

How can I get IDispatch pointer from QAxObject?


ps. Sorry for the poor English.

Hi,

Did you find any answer ? I am having the same kind of issue with PyQt.

Regards

Code:

---

IUnknown *iface = 0;
activeX->queryInterface(IID_IUnknown, (void**)&iface);
if (iface) {
    // use the interface
    iface->Release();
}

---

or

Code:

---

IDispatch*disp= 0;
activeX->queryInterface(IID_IDispatch, (void**)&disp);
if (disp) {
    // use the interface
    disp->Release();
}
