问题描述
我开始在 QGIS 3 上创建插件,我的插件需要 QTableView 中的进度条.我想弄清楚如何在 PyQt5 的 QTableView 中添加一列进度条.但是我找不到与我的问题相关的任何代码或资源.
I started creating a Plugin on QGIS 3 and my plugin requires Progress bars within a QTableView. I am trying to figure out how to add a column of progress bars within my QTableView in PyQt5. But I couldn't find any relevant code or resources regarding my problem.

w= self.tasklist_tabv
delegate = ProgressDelegate(w)
w.setItemDelegateForColumn(2, delegate)
w.setHorizontalHeaderLabels(["ID", "Name", "Progress"])
for r, (_id, _name, _progress) in enumerate(data):
it_id = QtGui.QTableWidgetItem(_id)
it_name = QtGui.QTableWidgetItem(_name)
it_progress = QtGui.QTableWidgetItem()
chkBoxItem = QtGui.QTableWidgetItem()
chkBoxItem.setFlags(QtCore.Qt.ItemIsUserCheckable | QtCore.Qt.ItemIsEnabled)
chkBoxItem.setCheckState(QtCore.Qt.Unchecked)
it_progress.setData(QtCore.Qt.DisplayRole+1000, _progress)
w.insertRow(w.rowCount())
for c, item in enumerate((it_id, it_name, it_progress)):
w.setItem(r, c, item)
for c, item in enumerate((it_id, it_name, chkBoxItem)):
w.setItem(r, c+1, item)
class ProgressDelegate(QtGui.QStyledItemDelegate):
def paint(self, painter, option, index):
progress = index.data(QtCore.Qt.DisplayRole+1000)
opt = QtGui.QStyleOptionProgressBar()
opt.rect = option.rect
opt.minimum = 0
opt.maximum = 100
opt.progress = progress
opt.text = "{}%".format(progress)
opt.textVisible = True
QtGui.QApplication.style().drawControl(QtGui.QStyle.CE_ProgressBar, opt, painter)
推荐答案
您可以使用委托:
from PyQt5 import QtCore, QtGui, QtWidgets
data = [("1", "Baharak", 10), ("2", "Darwaz", 60),
("3", "Fays abad", 20), ("4", "Ishkashim", 80),
("5", "Jurm", 100)]
class ProgressDelegate(QtWidgets.QStyledItemDelegate):
def paint(self, painter, option, index):
progress = index.data(QtCore.Qt.UserRole+1000)
opt = QtWidgets.QStyleOptionProgressBar()
opt.rect = option.rect
opt.minimum = 0
opt.maximum = 100
opt.progress = progress
opt.text = "{}%".format(progress)
opt.textVisible = True
QtWidgets.QApplication.style().drawControl(QtWidgets.QStyle.CE_ProgressBar, opt, painter)
if __name__ == '__main__':
import sys
app = QtWidgets.QApplication(sys.argv)
w = QtWidgets.QTableView()
delegate = ProgressDelegate(w)
w.setItemDelegateForColumn(2, delegate)
model = QtGui.QStandardItemModel(0, 3)
model.setHorizontalHeaderLabels(["ID", "Name", "Progress"])
for _id, _name, _progress in data:
it_id = QtGui.QStandardItem(_id)
it_name = QtGui.QStandardItem(_name)
it_progress = QtGui.QStandardItem()
it_progress.setData(_progress, QtCore.Qt.UserRole+1000)
model.appendRow([it_id, it_name, it_progress])
w.setModel(model)
w.show()
sys.exit(app.exec_())
PyQt4
from PyQt4 import QtCore, QtGui

def paint(self, painter, option, index):
progress = index.data(QtCore.Qt.UserRole+1000)
opt = QtGui.QStyleOptionProgressBar()
opt.rect = option.rect
opt.minimum = 0
opt.maximum = 100
if hasattr(progress, 'toPyObject'):
progress = progress.toPyObject()
opt.progress = progress
opt.text = "{}%".format(progress)
opt.textVisible = True
QtGui.QApplication.style().drawControl(QtGui.QStyle.CE_ProgressBar, opt, painter)
