How to change QPushButton text and background color
提问by alphanumeric
I am using following code to connect QMenuto QPushButton. When button is clicked a pull-down menu with multiple sub-menu's items is shown.
我正在使用以下代码连接QMenu到QPushButton. 单击按钮时，会显示包含多个子菜单项的下拉菜单。
button=QPushButton()
button.setText("Press Me")
font=QtGui.QFont()
button.setFont(font)
button.setSizePolicy(ToolButtonSizePolicy)
button.setPopupMode(QtGui.QToolButton.InstantPopup)
menu=QtGui.QMenu()
button.setMenu(menu)
menuItem1=menu.addAction('Menu Item1')
menuItem2=menu.addAction('Menu Item2')
Now depending on a condition I would like to customize QPushButtondisplay by giving it a text and background color. The following line of code (which is supposed to change background color) has no effect on QPushButtonconnected to QMenu.
现在根据条件，我想QPushButton通过给它一个文本和背景颜色来自定义显示。以下代码行（应该更改背景颜色）对QPushButton连接到 QMenu没有影响。
button.setStyleSheet('QPushButton {background-color: #A3C1DA}')
I would like to know how to change the background color of QPushButtonas well as button's text's color.
我想知道如何更改QPushButton按钮文本颜色的背景颜色。

from PySide import QtGui
app = QtGui.QApplication([])

menu = QtGui.QMenu()
menuItem1 = menu.addAction('Menu Item1')
menuItem2 = menu.addAction('Menu Item2')
button.setMenu(menu)
button.show()
app.exec_()

For those who still want to change color of button with the instruction
对于那些仍然想按照说明更改按钮颜色的人
button.setStyleSheet('QPushButton {background-color: #A3C1DA}')
and not able to do so, just modify the above instruction to
并不能这样做，只需将上述说明修改为
button.setStyleSheet('QPushButton {background-color: #A3C1DA; border: none}')
And it will change the button color, so the trick is to remove the border
它会改变按钮的颜色，所以诀窍是去除边框
