PyQt5组合框 当不可编辑和被按下时的不同边框尺寸
在这篇文章中,我们将看到如何在组合框不可编辑和被按下时设置不同的边框宽度,当我们为组合框设置边框时,虽然我们可以分别改变每个边框的颜色,但所有的边框都是一样的。不同的边框宽度只会在组合框不可编辑和组合框被按下时出现。
注意: 在setEditable方法的帮助下,可以使组合框变得可编辑。
为了做到这一点,我们必须改变与组合框相关的样式表,下面是样式表代码。
代码1
QComboBox::!editable:pressed
{
border : solid black;
border-width-top : 1px;
border-width-right : 5px;
border-width-bottom : 2px;
border-width-left : 10px;
}
代码2
QComboBox::!editable:pressed
{
border : solid black;
border-width : 1px 5px 2px 10px;
}
这两段代码执行类似的任务,只是代码1是代码2的扩展版本。
下面是执行情况
# importing libraries

class Window(QMainWindow):
def __init__(self):
super().__init__()

self.setWindowTitle("Python ")
# setting geometry
self.setGeometry(100, 100, 600, 400)
# calling method

# showing all the widgets
self.show()
# method for widgets
def UiComponents(self):
# creating a check-able combo box object
self.combo_box = QComboBox(self)
# setting geometry of combo box
self.combo_box.setGeometry(200, 150, 150, 80)
# making combo box editable
# self.combo_box.setEditable(True)
# geek list
geek_list = ["Sayian", "Super Sayian", "Super Sayian 2",
"Super Sayian B"]
# adding list of items to combo box
self.combo_box.addItems(geek_list)
# setting style sheet
# adding border to combo box
# adding different width border when
# it is non-editable and get pressed
self.combo_box.setStyleSheet("QComboBox"
"{"
"border : 5px solid black;"
"}"
"QComboBox::! editable:pressed"
"{"
"border : solid black;"
"border-width : 1px 5px 2px 10px;;"
"}")
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
window.show()
# start the app
sys.exit(App.exec())
