Question

I have an icon that is saved in a format:

//icon.h
extern const unsigned char icon[];

//icon.cpp
const unsigned char icon[]={0x17,0x3f,0x0c,....,0x10,0x06}

Now i want to add this icon to the status bar.

How do i do it?

Thank you.

Answer 1

First create a widget that loads the icon data, like a QLabel on which you set a QPixmap. What format is that image in? You will have to load it into your pixmap using one of the constructors, or you could try loading it with loadFromData().

Then add that widget to the status bar like so:

statusBar()->addWidget(yourIconWidget);

Have a look at statusBar(), addWidget() and addPermanentWidget().

An example of how to create the widget could be:

QPixmap *pixmap = new QPixmap;

// Note that here I don't specify the format to make it try to autodetect it, 
// but you can specify this if you want to. 
pixmap->loadFromData(icon, sizeof(icon) / sizeof(unsigned char));

QLabel *iconLbl = new QLabel;
iconLbl->setPixmap(pix);

statusBar()->addWidget(iconLbl);

Specifying the format, as I mentioned above, is elaborated upon here.
