我想复制 qt 表的选定部分，包括标题。默认的qt表复制仅复制一个单元格，而我需要整个选择，可以是多列和多行。我从不同的地方（主要是here）将一些代码拼接在一起，它似乎工作得很好，只是它只复制单元格（数据），而不是标题。我还需要一些帮助来获取选择的标题。这是我的瘦身样本：
from PyQt4 import QtGui, QtCore
import sys
class MainWidget(QtGui.QWidget):
def __init__(self, parent=None):
super(MainWidget, self).__init__(parent)
self.table = QtGui.QTableWidget(parent=self)
self.table.setColumnCount(2)
self.table.setRowCount(2)
self.table.setHorizontalHeaderLabels(['col1','col2'])
self.table.setVerticalHeaderLabels(['row1','row2'])
self.table.setItem(0,0,QtGui.QTableWidgetItem('foo'))
self.table.setItem(0,1,QtGui.QTableWidgetItem('bar'))
self.table.setItem(1,0,QtGui.QTableWidgetItem('baz'))
self.table.setItem(1,1,QtGui.QTableWidgetItem('qux'))
layout = QtGui.QGridLayout()
layout.addWidget(self.table, 1, 0)
self.setLayout(layout)
self.clip = QtGui.QApplication.clipboard()
def keyPressEvent(self, e):
if (e.modifiers() & QtCore.Qt.ControlModifier):
selected = self.table.selectedRanges()
if e.key() == QtCore.Qt.Key_C: #copy
s = ""
for r in xrange(selected[0].topRow(), selected[0].bottomRow()+1):
for c in xrange(selected[0].leftColumn(), selected[0].rightColumn()+1):
try:
s += str(self.table.item(r,c).text()) + "\t"
except AttributeError:
s += "\t"
s = s[:-1] + "\n" #eliminate last '\t'
self.clip.setText(s)
if __name__ == '__main__':
# Initialize the application
app = QtGui.QApplication(sys.argv)
mw = MainWidget()
mw.show()
app.exec_()
示例表如下所示：
col1 col2
row1 foo bar
row2 baz qux
例如，如果我选择
barbux\t col2\n
row1 \t bar\n
row2 \t qux\n
我的实际案例有很多列和行。我的困难在于找出所选单元格的标题；我可以处理格式。非常感谢任何帮助或建议。预先感谢！
线索在标题项中：
class MainWidget(QtGui.QWidget):
def __init__(self, parent=None):
super(MainWidget, self).__init__(parent)
self.table = QtGui.QTableWidget(parent=self)
self.table.setColumnCount(2)
self.table.setRowCount(2)
self.table.setHorizontalHeaderLabels(['col1','col2'])
self.table.setVerticalHeaderLabels(['row1','row2'])
self.table.setItem(0,0,QtGui.QTableWidgetItem('foo'))
self.table.setItem(0,1,QtGui.QTableWidgetItem('bar'))
self.table.setItem(1,0,QtGui.QTableWidgetItem('baz'))
self.table.setItem(1,1,QtGui.QTableWidgetItem('qux'))
layout = QtGui.QGridLayout()
layout.addWidget(self.table, 1, 0)
self.setLayout(layout)
self.clip = QtGui.QApplication.clipboard()
def keyPressEvent(self, e):
if (e.modifiers() & QtCore.Qt.ControlModifier):
selected = self.table.selectedRanges()
if e.key() == QtCore.Qt.Key_C: #copy
s = '\t'+"\t".join([str(self.table.horizontalHeaderItem(i).text()) for i in xrange(selected[0].leftColumn(), selected[0].rightColumn()+1)])
s = s + '\n'
for r in xrange(selected[0].topRow(), selected[0].bottomRow()+1):
s += self.table.verticalHeaderItem(r).text() + '\t'
for c in xrange(selected[0].leftColumn(), selected[0].rightColumn()+1):
try:
s += str(self.table.item(r,c).text()) + "\t"
except AttributeError:
s += "\t"
s = s[:-1] + "\n" #eliminate last '\t'
self.clip.setText(s)
我知道这个问题有点老了，但是对于正在寻找一种解决方案的人来说，允许他们选择不一定连接的多个范围，以下代码对我有用。
def copy_selection_to_clipboard(self) -> None:
def intersects_with_ranges(ranges: list[tuple[int, int, int, int]], row: int, col: int) -> bool:
# Checks if given row and col is in any given range
for range_ in ranges:
top, left, bottom, right = range_
in_between_rows = row >= top and row <= bottom
in_between_cols = col >= left and col <= right
if in_between_rows and in_between_cols:
return True
return False
model = self.model()
ranges = [(r.topRow(), r.leftColumn(), r.bottomRow(), r.rightColumn()) for r in self.selectedRanges()]
is_whole_table_selected = (
len(ranges) == 1
and ranges[0][0] == 0
and ranges[0][1] == 0
and ranges[0][2] == self.rowCount() - 1
and ranges[0][3] == self.columnCount() - 1
)
row_start = min(ranges, key=lambda r: r[0])[0]
col_start = min(ranges, key=lambda r: r[1])[1]
row_end = max(ranges, key=lambda r: r[2])[2]
col_end = max(ranges, key=lambda r: r[3])[3]
rows = []
for row_idx in range(row_start, row_end + 1):
row = []
for col_idx in range(col_start, col_end + 1):
# empty value for not selected columns
if not is_whole_table_selected and not intersects_with_ranges(ranges, row_idx, col_idx):
value = ""
else:
# could also use EditRole if you have a customed model and want the raw value
value = model.index(row_idx, col_idx).data(QtCore.Qt.ItemDataRole.DisplayRole)
row.append(value)
rows.append(row)
if is_whole_table_selected:
rows.insert(0, [self.horizontalHeaderItem(i).text() for i in range(self.columnCount())])
clipboard_text = "\r\n".join("\t".join(row) for row in rows)
QtWidgets.QApplication.clipboard().setText(clipboard_text)
然后只需向表中添加一个操作即可
Ctrl + Caction = self.addAction("Auswahl kopieren")
action.setShortcut(QtGui.QKeySequence("Ctrl+C"))
action.triggered.connect(self.copy_selection_to_clipboard)
