QWidget not show after calls show()
原标题:QWidget not showing after calling show()

在我的应用中,我有一个在我打电话show(<>show(>后没有显示的QWidget,即使isible 回归true

这一植被是主要应用窗口活动产生的。 但是,当它自食其力时,即它是唯一的植被时,它通常会显示出来。

任何人都知道会是什么原因?

在我看来,其他植被通常只是给我带来麻烦。 事实上,根据前几版Qt4(宽大的记忆)进行罚款。

the code for the widget is here

更新:窗户似乎出现,立即销毁。

最佳回答

The relevant code is in hidx/GUI/main.py:

@pyqtSignature("")
def on_actionScatterplot_Matrix_activated(self):
    ...
    spm = scatmat.ScatMat(pars, self.currentdbname)
    print "==>", spm.pw.isVisible()
    spm.pw.hide()
    spm.pw.showMaximized()
    print spm.pw.size()
    print "==>", spm.pw.isVisible()

@pyqtSignature("int")
def on_rowStart_valueChanged(self, p0):
    ...

on_actionScatterplot_Matrix_startd上,你设立了<代码>ScatMat的事例,但没有提到。 因此,窗户将简要展示,然后在功能完成后立即收集垃圾。
