如何显示QDialog
如何显示QDialog
提问于 2013-12-18 23:49:50
我需要在QWidget中按下QWidget后显示一个查找对话框，其中包含一个QTableView。“查找”对话框将在表的第一列中搜索以找到匹配项。
我可以在使用以下代码按下QMessageBox之后显示Ctrl+F：
class Widget(QWidget):
def __init__(self,md,parent=None):
QWidget.__init__(self,parent)
layout=QVBoxLayout(self)
# initially construct the visible table
tv = QTableView()
# uncomment this if the last column shall cover the rest
tv.horizontalHeader().setStretchLastSection(True)
tv.show()
# set black grid lines
self.setStyleSheet("gridline-color: rgb(39, 42, 49)")
# construct the Qt model belonging to the visible table
model = NvmQtModel(md)
tv.setModel(model)
tv.resizeRowsToContents()
tv.resizeColumnsToContents()
# set the shortcut ctrl+F for find in menu
shortcut = QShortcut(QKeySequence('Ctrl+f'), self)
shortcut.activated.connect(self.handleFind)
# delegate for decimal
delegate = NvmDelegate()
tv.setItemDelegate(delegate)
self.setGeometry(200,200,600,600) # adjust this later
layout.addWidget(tv)
# set window title
self.setWindowTitle("TITLE")
# find function: search in the first column of the table
def handleFind(self):
reply = QMessageBox.question(
self, 'Find', 'Find Dialog',
QMessageBox.Yes | QMessageBox.No)
if reply == QMessageBox.Yes:
print('Yes')
else:
print('No')然后，我将QMessageBox更改为QDialog，但现在它无法工作。如果你能告诉我哪里做得不对，我将不胜感激：
class Widget(QWidget):
def __init__(self,md,parent=None):
QWidget.__init__(self,parent)
layout=QVBoxLayout(self)
# initially construct the visible table
tv = QTableView()
# uncomment this if the last column shall cover the rest
tv.horizontalHeader().setStretchLastSection(True)
tv.show()
# set black grid lines
self.setStyleSheet("gridline-color: rgb(39, 42, 49)")
# construct the Qt model belonging to the visible table
model = NvmQtModel(md)
tv.setModel(model)
tv.resizeRowsToContents()
tv.resizeColumnsToContents()
# set the shortcut ctrl+F for find in menu
shortcut = QShortcut(QKeySequence('Ctrl+f'), self)
shortcut.activated.connect(self.handleFind)
# delegate for decimal
delegate = NvmDelegate()
tv.setItemDelegate(delegate)
self.setGeometry(200,200,600,600) # adjust this later
layout.addWidget(tv)
# set window title
self.setWindowTitle("TITLE")
# find function: search in the first column of the table
def handleFind(self):
findDialog = QDialog()
findLabel = QLabel("Find what", findDialog)
findField = QLineEdit(findDialog)
findButton = QPushButton("Find", findDialog)
closeButton = QPushButton("Close", findDialog)
findDialog.show()回答 1

如果希望对话框是模态对话框，请调用findDialog.exec_()
from PyQt4.QtGui import *
def handleFind():
findDialog = QDialog()
#findDialog.setModal(True)
findLabel = QLabel("Find what", findDialog)
findField = QLineEdit(findDialog)
findButton = QPushButton("Find", findDialog)
closeButton = QPushButton("Close", findDialog)
#findDialog.show()
findDialog.exec_()
app = QApplication([])
b = QPushButton("click me")
b.clicked.connect(handleFind)
b.show()
app.exec_()页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
