I have a QVBoxLayout where I put some buttons. I wrote a function to remove a button, but when I do it, the box doesn't adapt its size to the content. Here is a piece of the removal function:
for each_difference in differences_remove:
old_index = self.all_tags.index(each_difference)
print("old" + str(old_index))
self.vbox_all_tags.removeWidget(self.liste_pressoirs[old_index])
del self.liste_pressoirs[old_index]
I would like self.vbox_all_tags to adapt its size to the new content after I remove a button. How would you do that ?
Kindly.
Just call adjustSize
on your widget after removing the button, here is a demonstration:
#!/usr/bin/env python
#-*- coding:utf-8 -*-
from PyQt4 import QtCore, QtGui
class MyWindow(QtGui.QWidget):
_buttons = []
def __init__(self, parent=None):
super(MyWindow, self).__init__(parent)
self.pushButtonRemove = QtGui.QPushButton(self)
self.pushButtonRemove.setText("Remove A Button!")
self.pushButtonRemove.clicked.connect(self.on_pushButtonRemove_clicked)
self.widgetButtons = QtGui.QWidget(self)
self.layoutButtons = QtGui.QHBoxLayout(self.widgetButtons)
self.layout = QtGui.QVBoxLayout(self)
self.layout.addWidget(self.pushButtonRemove)
self.layout.addWidget(self.widgetButtons)
for buttonNumber in range(3):
pushButton = QtGui.QPushButton()
pushButton.setText("Button {0}".format(buttonNumber))
self._buttons.append(pushButton)
self.layoutButtons.addWidget(pushButton)
@QtCore.pyqtSlot()
def on_pushButtonRemove_clicked(self):
if self._buttons:
pushButton = self._buttons[-1]
self._buttons.pop()
self.layoutButtons.removeWidget(pushButton)
pushButton.deleteLater()
self.widgetButtons.adjustSize()
self.adjustSize()
if __name__ == "__main__":
import sys
app = QtGui.QApplication(sys.argv)
app.setApplicationName('MyWindow')
main = MyWindow()
main.show()
sys.exit(app.exec_())
