QToolbar - change icon at runtime ?

Hi,

In my main window, I have a toolbar with an action. This action/button has an icon (a png image) that is visible in the QT Creator form designer. But when I run the application, I see no image !!! Can you tell me why ?

Also, at run time, with code, I would like to change the image of the toolbar button. Is it possible ? And how to do this ?

Thanks for your help

Has probably to do with path resolution of the image.
But without code its hard to tell exactly.

QAction::setIcon() ?

Thanks,

I have put my images in ressources and all is fine, it is displayed now.

In order to change the icon I have do this :

Code:

---

actions().first()->setIcon(QIcon(":/images/pause.png"));

---

But it crash :-P

The problem is that actions(); return an empty list !

use the name of the action instead of ations()->first()

Thanks,

How can I use the name of the action, there is no findAction("") method ?

Also actions() is empty in my main window ! do you know why ?

somewhere in your code must be something like this:

Code:

---

QAction myAction;

---

if you create your form via QtDesigner, you have to create all actions via the action editor. there you give each action a name. You can access your actions the same way as each other gui-element.

Code:

---

ui->toolBar->actions().first()->setIcon(QIcon(":/images/pause.png"));
