[SOLVED] Setting 2 colors in Mainwindows Statusbar

Woody

Hi all,

I have a little issue and finding it hard to solve, if it is even possible to so.

When I want to give a warning to the user, I want the statusbar to display a message in red like so:
!http://wouterverbruggen.be/img/qt/red-status.jpg(Red status)!

But when I want to give information it has to be black:
!http://wouterverbruggen.be/img/qt/black-status.jpg(Black Status)!

Is it possible to set a default color, and when I want to give a warning just change it?

Thanks in advance.

Hi,
I think if you are setting a QLabel to you statusbar then you can use "stylesheets":http://doc.qt.nokia.com/4.7-snapshot/stylesheet-examples.html for eg

@QLabel *lblHello = new QLabel(this);
lblHello->setText("Hi How are you");
lblHello->setStyleSheet("QLabel { color: red;}");
this->statusBar()->addPermanentWidget(lblHello,1);@

This changes the color to red. So you can customize the color based on your requirement.

Woody

That idd helped to solve the issue, I thank you for that!

But how can you make it empty again after lets say 2sec?

So if I give a warning it has to disappear after 2sec, how is that done then?

Sam

So you mean to say that the color should change after 2 sec or the message should also change i.e from waring to information ?

Woody

No, I want to make the statusbar empty, so nothing is showing. Show the warning for 2 sec and then make the statusbar empty again.

Sam

Well there is something like "showMessage":http://qt-project.org/doc/qt-4.8/qstatusbar.html#showMessage where you can set message as well as the timer. But I dont know whether it supports rich text or not.

Other way you can use a QTimer eg.

@QTimer *timer = new QTimer(this);
connect(timer, SIGNAL(timeout()), this, SLOT(doSomething()));
timer->start(1000);

lblHello = new QLabel(this);
lblHello->setText("Hi How are you");
lblHello->setStyleSheet("QLabel { color: red;}");
this->statusBar()->addPermanentWidget(lblHello,1);@

and in the doSomething() slot you can remove your widget from the statusbar.

Not yet tested!!! check if this works :)

I was trying it with the timer. And that did the job.

Solution:
@m_timer = new QTimer(this);
m_timer->setInterval(2000);

connect(m_timer, SIGNAL(timeout()), this, SLOT(timerTimeout()));@

Set my statusmessage:
@m_warningLabel = new QLabel(this);
m_warningLabel->setText(text);
m_warningLabel->setStyleSheet("QLabel { color:red;}");

ui->statusBar->addWidget(m_warningLabel, 0);

m_timer->start();@

on timerTimeout:
@m_warningLabel->setVisible(false);
m_timer->stop();@

Thanks Soumitra!

You are welcome. :)
