Re: [Discuss-gnuradio] Include own GUI in existing QT windows

[Sebastian Müller]

Hi,

update on this topic: I figured out that passing the parent does not seem to be the problem. The important lines are in the <make> tag of the XML file, which result in the python flowgraph to:

> self.inspector_qtgui_sink_vf_0 = inspector.qtgui_inspector_sink_vf(4096)

> self._inspector_qtgui_sink_vf_0_win = sip.wrapinstance(self.inspector_qtgui_sink_vf_0.pyqwidget(), Qt.QWidget)

> self.top_layout.addWidget(self._inspector_qtgui_sink_vf_0_win)

I have copied all of the code concerning pyqwidget() from gr-qtwidget (at least I think so), but the flowgraph still fails with the error:

> self._inspector_qtgui_sink_vf_0_win = sip.wrapinstance(self.inspector_qtgui_sink_vf_0.pyqwidget(), Qt.QWidget)

> TypeError: must be integer<K>, not SwigPyObject

So it seems as if the PyObject* pyqwidget() is SWIGged, which is not necessary here. Can anyone tell me how to fix this error?

Cheers,

Sebastian

Hi list,

can anyone help me with this? I'm trying to build an own QT GUI, which opens in an own window so far. I want to include my GUI in existing QT windows (like all the gr-qtgui blocks do) so that there is only one window with all the QT content in it.

So far I have configured the <make> call in the GRC XML like this:

<make>#set $win = 'self._%s_win'%$id

inspector.qtgui_inspector_sink_vf($fft_len)

self._$(id)_win = sip.wrapinstance(self.$(id).pyqwidget(), Qt.QWidget)

$(gui_hint()($win))</make>

qtgui_inspector_sink_vf_impl constructor looks like this:

qtgui_inspector_sink_vf_impl(int fft_len, QWidget *parent);

This block creates an instance of "inspector_plot" which inherits QWidget class:

inspector_plot(int fft_len, std::vector<float> *buffer, QWidget* parent) : QWidget(parent).

I also created a PyObject* pyqwidget() in the public header and the impl header and source files (copied from gr-qtgui). When trying to start, the python flowgraph fails because it does not seem to find pyqwidget(): AttributeError: 'qtgui_inspector_sink_vf_sptr' object has no attribute 'pyqwidget'.

Would be great if someone could help with what I'm missing.

Cheers,

Sebastian
