向状态栏添加图标-Qt

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 .
