OS X: Figures open and close immediately

[Jan Beneke]

When opening a figure it flashes and closes immediately. It can be shown afterwards.

Example: plot

fig = figure()
fig.plot(dataObject.randN([100,200]))

Figure flashes and closes.

The command

fig.show()

shows the plot dialog as requested.

Example: liveImage

The snippet

cam = dataIO("DummyGrabber")

cam.setParam("bpp",8)
print("width:", cam.getParam("sizex"))
print("height:", cam.getParam("sizey"))

liveImage(cam)

returns

width: 640
height: 480
(5, PlotItem(UiItem(class: Itom2dQwtPlot, name: plot0x0)))

Again, the dialog flashes and disappears immediately. The debug console output is:

[Jan Beneke]

plot() closes in:

• uiOrganizer.cpp:2816: retval += fig->plot(dataCont.getDataObject(), areaRow, areaCol, className, &destWidget);
• figureWidget.cpp::326: changeCurrentSubplot(idx);
• figureWidget.cpp::717: addToolBar(i->toolbar, key_, i->area, i->section);
• abstractDockWidget::554: m_pWindow->insertToolBar(m_dockToolbar, tb);

The same happens when using m_pWindow->addToolBar(tb); in abstractDockWidget::554.

[Jan Beneke]

Adding

#ifdef __APPLE__
    // Bug fix: Issue #35
    // OS X hides windows/ dialog after adding a toolbar
    m_pWindow->show();
#endif // __APPLE__

at the end of

AbstractDockWidget::addToolBar()

fixes the issue.
