Qt-如何自定义QTableWidget的复选框

Question

I've tried to set some style for check box for Qt. I've already knew that QtTableWidget has QCheckbox. but problem is I have no idea how to set style for checkbox of QtTableWidget.

QTableWidgetItem *checkBoxItem = new QTableWidgetItem();
checkBoxItem->setCheckState(Qt::Unchecked);
table->setItem(row, column, checkBoxItem);

When I use setStyleSheet for checkBox :

checkBoxItem->setStyleSheet("...");

I have an error: 'class QTableWidgetItem' has no member named 'setStyleSheet'

Edited : I want to do some operation with checkBox. Here is complete code for first QTableWidgetItem:

for (int i = 0; i < 4; ++i)
    m_tableWidget->setRowHeight(i, 3 * em);


QTableWidgetItem *item1 = new QTableWidgetItem(tr("Show Message Preview"));

if (CGlobalZone::m_showMsgPreview)
    item1->setCheckState(Qt::Checked);

else
    item1->setCheckState(Qt::Unchecked);

item1->setFlags(Qt::ItemIsEnabled);
m_tableWidget->setItem(0, 0, item1);

Answer 1

You can style the indicators with QAbstractItemView::indicator { ... } (eg QTableView::indicator:checked, QTableView::indicator:unchecked etc).

You can't apply style directly to the QTableItemWidget, but you can put a stylesheet on the QTableWidget itself or a parent of it.

Answer 2

Assuming, you already have a table widget with at least one column and at least one row:

QCheckBox *cb = new QCheckBox(tr("Check me"));
cb->setStyleSheet("background-color: rgb(0, 85, 0);");
tableWidget->setCellWidget(0, 0, cb);
