下面的代码创建一个QListWidget,其中QListWidgetItem分配了一个拇指图像。
如果你能展示一下如何在QListWidgetItem周围做一个彩色边框,我将不胜感激
这是一张照片,展示了一个概念:
from PyQt4 import QtGui, QtCore
import sys, os
class MyClassItem(QtGui.QListWidgetItem):
def __init__(self, parent=None):
super(QtGui.QListWidgetItem, self).__init__(parent)
class ThumbListWidget(QtGui.QListWidget):
def __init__(self, type, parent=None):
super(ThumbListWidget, self).__init__(parent)
self.setIconSize(QtCore.QSize(64, 64))
class Dialog_01(QtGui.QMainWindow):
def __init__(self):
super(QtGui.QMainWindow,self).__init__()
self.listItems={}
myQWidget = QtGui.QWidget()
myBoxLayout = QtGui.QVBoxLayout()
myQWidget.setLayout(myBoxLayout)
self.setCentralWidget(myQWidget)
self.listWidgetA = ThumbListWidget(self)
for i in range(7):
listItemAInstance=MyClassItem()
name='A'+'%04d'%i
listItemAInstance.setText(name)
listItemAInstance.setBackgroundColor(QtCore.Qt.darkGray)
if i%2: listItemAInstance.setBackgroundColor(QtCore.Qt.gray)
icon=self.getIcon(name)
listItemAInstance.setIcon( icon )
self.listWidgetA.addItem(listItemAInstance)
listItemBInstance=MyClassItem()
name='B'+'%04d'%i
listItemBInstance.setText(name)
icon=self.getIcon(name)
listItemBInstance.setIcon( icon )
myBoxLayout.addWidget(self.listWidgetA)
def getIcon(self, name):
thumbpath=os.path.expanduser("~")+'/thumbs/' +name+'/'+name+'.jpg'
if not thumbpath: return
if not os.path.exists(os.path.dirname(thumbpath)):
os.makedirs(os.path.dirname(thumbpath))
img = QtGui.QImage(64, 64, QtGui.QImage.Format_RGB32)
img.fill(QtGui.QColor(96,96,96))
painter = QtGui.QPainter(img)
font = painter.font()
font.setBold(True)
font.setPointSize(18)
painter.setPen(QtGui.QColor('black'))
painter.setFont(font)
painter.drawText(img.rect(), QtCore.Qt.AlignCenter, name)
painter.end()
img.save(thumbpath, 'JPG')
icon = QtGui.QIcon( thumbpath )
pixmap = icon.pixmap(64, 64)
icon = QtGui.QIcon(pixmap)
return icon
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
dialog_1 = Dialog_01()
dialog_1.show()
dialog_1.resize(720,480)
sys.exit(app.exec_())
最佳答案
从QWidget
派生的每个类都支持CSS样式。你能做的就是这样:
lwi = QListWidget()
lwi.setStyleSheet("QListWidget::item { border: 0px solid red }")
有关更多信息,请参见http://qt-project.org/doc/qt-4.8/qwidget.html#styleSheet-prop
您也可以设置整个应用程序的样式,但通过将其作为前缀,将样式的某个部分仅应用于
QListWidgetItem
。我发现C++例子:
app.setStyleSheet("QListWidget { background: red; } QListWidget::item { background: yellow; } QListWidget::item:selected { background: blue; }");
关于python - 如何在QListWidgetItem周围绘制边框,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/24045554/
