问题描述
我对 PySide QTableWidget 有问题.我需要添加所有行图像预览的第一列.我正在尝试使用 QIcon 添加此内容:
I have problem with PySide QTableWidget. I need to add in first column of all rows image preview. I'm trying to add this using QIcon:
library_table.insertRow(index)
library_table.setItem(index, 1, QTableWidgetItem(file))
image = QIcon(self.sub_ad + file)
library_table.setItem(index, 0, QTableWidgetItem(image, ""))
但是图片很小.
我尝试使用 QSize、QPixmap 等,但没有任何成功,大小仍然相同.我怎样才能把这个上一张图片放大?
I was trying to use QSize, QPixmap etc. without any succes, size is still the same. How can I make this prev images bigger?
推荐答案
一个简单的解决方案是建立一个委托,使用 setItemDelegateForColumn() 在
方法:QTableWidget
中调整图标大小和设置
A simple solution is to establish a delegate where the icon is resized and set in the QTableWidget
using the setItemDelegateForColumn()
method:
from PySide import QtCore, QtGui
class IconDelegate(QtGui.QStyledItemDelegate):
def initStyleOption(self, option, index):
super(IconDelegate, self).initStyleOption(option, index)
option.decorationSize = option.rect.size()
class MainWindow(QtGui.QMainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
table_widget = QtGui.QTableWidget()
self.setCentralWidget(table_widget)
table_widget.setColumnCount(2)
table_widget.verticalHeader().setDefaultSectionSize(80)
for index, file in enumerate(("clear.png", "butterfly.png")):
table_widget.insertRow(table_widget.rowCount())
item1 = QtGui.QTableWidgetItem(QtGui.QIcon(file), "")
item2 = QtGui.QTableWidgetItem(file)
table_widget.setItem(index, 0, item1)
table_widget.setItem(index, 1, item2)
delegate = IconDelegate(table_widget)
table_widget.setItemDelegateForColumn(0, delegate)
if __name__ == '__main__':
import sys
app = QtGui.QApplication(sys.argv)
w = MainWindow()
w.show()
sys.exit(app.exec_())
