PyQT4 動態加載checkboxs，以及除去checkboxs

經過幾天的折騰終於弄好動態加載checkboxs，特此記錄:

 

首先上基礎UI文件。

    myapp = MainApp()
    myapp.show()
    sys.exit(app.exec_())

其中，此方法為掃描一個目錄，將相關結果取回，並生成checkbox

 

 

  def scan_files(self):
        root_dir=unicode(self.ui.lineEdit.text())
        if os.path.isdir(root_dir):
            self.app_start()
            self.clear_checkboxs(self.scrollArea)
            self.scan_thread.render(root_dir)
            self.scan_thread.wait()
            l=self.scan_thread.check
            n=10
            self.scrollAreaWidgetContents.setGeometry(QtCore.QRect(0, 0, 629, 239))
            self.scrollAreaWidgetContents.setObjectName(_fromUtf8("scrollAreaWidgetContents"))
 
            for i  in l:
                name= os.path.splitext(os.path.split(i)[-1])[-2]+"      (%s)"%i
                
                self.checkBox = QtGui.QCheckBox(self.scrollAreaWidgetContents)
                self.checkBox.setVisible(True)
                self.checkBox.setGeometry(QtCore.QRect(10, n, 600, 16))
                #self.checkBox.setObjectName(_fromUtf8("checkBox"))
                self.checkBox.setText(_translate("Frame", name, None))
                
                n+=30
             
                self.checkBoxs_and_path.append((self.checkBox,i))
            self.scrollArea.setWidget(self.scrollAreaWidgetContents)
            #print self.checkBoxs
        else:
            self.ui.textEdit.append(u'請先選擇一個有效的目錄')
        self.app_end()
                

其中此段是添加checkboxs。

for i  in l:
                name= os.path.splitext(os.path.split(i)[-1])[-2]+"      (%s)"%i
                
                self.checkBox = QtGui.QCheckBox(self.scrollAreaWidgetContents)
                self.checkBox.setVisible(True)
                self.checkBox.setGeometry(QtCore.QRect(10, n, 600, 16))
                #self.checkBox.setObjectName(_fromUtf8("checkBox"))
                self.checkBox.setText(_translate("Frame", name, None))
                
                n+=30
             
                self.checkBoxs_and_path.append((self.checkBox,i))
            self.scrollArea.setWidget(self.scrollAreaWidgetContents)

 

而self.clear_checkboxs(self.scrollArea)把前一次掃描的結果清除隱藏。self.checkBox.setVisible(True)將本次出現的checkbox設為可見。之前用checkBox.deleteLater()這個方法一直沒有起作用。
