copied!<p>If you want the copy paste ability that QErrorMessage would have, you could create your own custom QDialog. First I would make a dialog.ui with a QTextEdit (textEdit) and a QPushButton (okButton). Make sure you name the dialog object in the .ui something meaningful (MessageDialog in this case). The code could be something like this:</p> <p>In your messagedialog.h:</p> <pre><code>class MessageDialog : public QDialog, public Ui::MessageDialog { Q_OBJECT private: Ui::MessageDialog *ui; public: MessageDialog(QWidget * parent = 0, QString msg = "", uint w = 200, uint h = 100); private slots: void on_okButton_clicked(); }; </code></pre> <p>In your messagedialog.cpp:</p> <pre><code>MessageDialog::MessageDialog(QWidget *parent, QString msg, uint w, uint h) : QDialog(parent), ui(new Ui::MessageDialog) { ui->setupUi(this); this->setFixedSize(w, h); this->ui->textEdit->setFixedSize( (w - 20), (h - 50) ); this->ui->textEdit->setGeometry( (this->geometry().left() + 10), 10, (ui->okButton->size().width()), (ui->okButton->size().height())); // I personally like to get rid of the ? next to close in the upper right, minimize, and maximize this->setWindowFlags(windowFlags() & ~Qt::WindowContextHelpButtonHint); this->setWindowFlags(windowFlags() & ~Qt::WindowMinimizeButtonHint); this->setWindowTitle("Message"); this->ui->textEdit->setText(msg); this->ui->okButton->setGeometry( (this->geometry().center().x() - (this->ui->okButton->width() / 2) ), (this->geometry().bottom() - (this->ui->okButton->height())) - 5, (ui->okButton->size().width()), (ui->okButton->size().height())); this->setFocus(); } void MessageDialog::on_okButton_clicked() { this->close(); } </code></pre> <p>Then wherever you want to use it:</p> <pre><code>QDialog *messageDialog = new MessageDialog(this, msg); messageDialog->exec(); </code></pre>
