我需要将 LineEdit 和 Button 组合成这样的元素,并且我希望 lineEdit 像往常一样工作。但是当我点击lineEdit时,光标没有出现,只有当我点击3次时,光标才会出现但不闪烁。
之后,我单击另一个位置以失去 lineEdit 的焦点,我希望光标不再存在,但光标仍然存在。
我知道问题出在我的样式表中,但我不知道在哪里。你们能帮帮我吗?
这是我的代码:
MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow)
{
ui->setupUi(this);
ui->lineEdit1->setPlaceholderText("another LineEdit to lose focus for the LineEdit below");
QHBoxLayout *lineEditWithButtonForm = new QHBoxLayout( this );
lineEditWithButtonForm->setSpacing(0);
lineEditWithButtonForm->setContentsMargins(0,0,0,0);
ui->m_lineEdit->setContentsMargins(10,0,10,0);
ui->m_lineEdit->setFixedHeight( 25 );
ui->m_lineEdit->setStyleSheet("QLineEdit{ padding-left: 10px; padding-right: 10px; border-width: 1px 0px 1px 1px; border-style: solid; border-color: rgb(204,204,204); }");
lineEditWithButtonForm->addWidget(ui->m_lineEdit);
ui->m_button->setFixedHeight( 25 );
ui->m_button->setCursor( QCursor( Qt::PointingHandCursor ) );
ui->m_button->setFocusPolicy(Qt::ClickFocus);
ui->m_button->setStyleSheet( "QAbstractButton{ border-width: 1px 1px 1px 0px; border-style: solid; border-color: rgb(204,204,204); }");
lineEditWithButtonForm->addWidget(ui->m_lineEdit);
ui->m_lineEdit->installEventFilter( this );
}
bool MainWindow::eventFilter( QObject *obj, QEvent *event )
{
if ( obj == ui->m_lineEdit )
{
if ( event->type() == QEvent::FocusIn )
{
ui->m_lineEdit->setStyleSheet( "QLineEdit{padding-left: 10px; padding-right: 10px; border-width: 1px 0px 1px 1px; border-style: solid; border-color:rgb(249,125,25)}" );
ui->m_button->setStyleSheet( "QAbstractButton{ border-width: 1px 1px 1px 0px; border-style: solid; border-color: rgb(249,125,25)}" );
return true;
}
else if ( event->type() == QEvent::FocusOut)
{
ui->m_lineEdit->setStyleSheet( "QLineEdit{ padding-left: 10px; padding-right: 10px; border-width: 1px 0px 1px 1px; border-style: solid; border-color: rgb(204,204,204)}" );
ui->m_button->setStyleSheet( "QAbstractButton{ border-width: 1px 1px 1px 0px; border-style: solid; border-color: rgb(204,204,204) } ");
return true;
}
else
{
return false;
}
}
else
{
return MainWindow::eventFilter( obj, event );
}
}
