Display compiler output to a textbrowser in GUI

ghkraju

Hi,

I wanted to display my console/compiler output in a textBrowser in GUI. I have used qInstallMessageHandler to catch the messages and can able to print to a text file successfully but i am unable to print it in the textBrowser.

I tried working with signals and slots but i am unable to get it. Any ideas/help would be much appreciated.

Thanks in Advance,
Hemanth

Hi and welcome to devnet,

Take a look at this Wiki article. It shows a possible implementation.

Hope it helps.

Thank you.... SGaist Finally I found a way to display the compiler output back to my GUI. In the next post I will try to put the code for future reference to others.

I have used the following way to solve:

// Keep Handler before the "QApplication" function in main.cpp
qInstallMessageHandler(myMessageOutput);
QApplication a(argc, argv);

// w is my MainWindow here
// Message Handler outside main method is as follows
void myMessageOutput(QtMsgType type, const QMessageLogContext & context, const QString & msg)
{
if(w){
QDateTime dTime(QDateTime::currentDateTime());
QString timeStr(dTime.toString("dd-MM-yyyy HH:mm:ss:zzz"));
QString contextString(QString("(%1, %2)").arg(context.file).arg(context.line));

 QString totmsg;
 totmsg += timeStr + " " + contextString + ": " + msg;
 w->updateLog(totmsg);

}

// tBrowser is my textarea in a widget in the main window
void MainWindow::updateLog(const QString &msg){
ui->widget->tBrowser->append(msg);
}

I hope this helps. If in case of any issues please comment..... I can help as much as I can
