在QMessageBox中设置多个复选框
在QMessageBox中设置多个复选框
提问于 2021-08-10 20:10:58
我正在尝试在一个QMessageBox中设置两个QCheckBox。只出现第二个复选框。我该如何实现这一点？只创建一个定制的QDialog是不是更好？
void TextEditor::actionConfigure_triggered()
{
QCheckBox *checkbox = new QCheckBox("Cursor to end of file");
QCheckBox *geometryCheckBox = new QCheckBox("Save and restore geometry");
QMessageBox msgBox(this);
msgBox.setStandardButtons(QMessageBox::Apply | QMessageBox::Discard | QMessageBox::Reset | QMessageBox::RestoreDefaults);
msgBox.setDefaultButton(QMessageBox::Apply);
msgBox.setCheckBox(checkbox);
msgBox.setCheckBox(geometryCheckBox);
checkbox->setToolTip("Option to move cursor to end of text on file open");
geometryCheckBox->setToolTip("Option to save and restore geometry on open / close");
int ret = msgBox.exec();
switch (ret) {
case QMessageBox::Apply:
// Save was clicked
break;
case QMessageBox::Discard:
// Don't Save was clicked
break;
case QMessageBox::Reset:
// Cancel was clicked
break;
case QMessageBox::RestoreDefaults:
// Restore defaults
break;
default:
// should never be reached
break;
}

默认情况下，QMessageBox只允许放置QCheckBox，因此如果添加新的QCheckBox，它将替换以前的one。一种可能的解决方案是直接将QCheckBox注入布局：
QCheckBox *checkbox = new QCheckBox("Cursor to end of file");
QCheckBox *geometryCheckBox = new QCheckBox("Save and restore geometry");
QMessageBox msgBox(this);
msgBox.setStandardButtons(QMessageBox::Apply | QMessageBox::Discard | QMessageBox::Reset | QMessageBox::RestoreDefaults);
msgBox.setDefaultButton(QMessageBox::Apply);
checkbox->setToolTip("Option to move cursor to end of text on file open");
geometryCheckBox->setToolTip("Option to save and restore geometry on open / close");
msgBox.setCheckBox(checkbox);
QGridLayout *grid = qobject_cast<QGridLayout *>(msgBox.layout());
int index = grid->indexOf(checkbox);
int row, column, rowSpan, columnSpan;
grid->getItemPosition(index, &row, &column, &rowSpan, &columnSpan);
grid->addWidget(geometryCheckBox, row + 1, column, rowSpan, columnSpan);
int ret = msgBox.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
