QTabBar??

[anupamgee]

hi all,
I want to set image on a tab of a tabbar .I want to create tab as the same size of image.
But size of tab i m creating is bigger than that of image........
I used the following code

QTabBar *tabbar=new QTabWidget(this);
QPixmap image(":/images/abc.png");
QIcon icon(image);
tabbar->addTab(icon," ");
QSize size(image.width(),image.height());
tabbar->setIconSize(size);

QTabBar *tabbar=new QTabWidget(this);
QPixmap image(":/images/abc.png");
QIcon icon(image);
tabbar->addTab(icon," ");
QSize size(image.width(),image.height());
tabbar->setIconSize(size);

To copy to clipboard, switch view to plain text mode 

How to do????

You don't really describe your problem, but I suspect that you want to stretch your image. This can be done, however, I've run into issues with the QTabBar where I've wanted special looks and I've always ended up subclassing it and reimplementing the painting - just to get control of the size of each tab, etc.

thnx for reply,
I want to create tab of same size of my image..
how to do that? I m using the code mentioned in previous post.
but using that code i m not getting the tab size as that of image.

In what contents are you using your tabbar? As a part of a QTabWidget, or in another setting.

As a part of QTabWidget...

I seem to recall that you could set the QTabBar widget for a QTabWidget (cannot seem to locate the method in the 4.5 docs). In that case, you can reimplement the virtual methods at the bottom of this details section: http://doc.trolltech.com/4.5/qtabbar.html#details . Especially: http://doc.trolltech.com/4.5/qtabbar.html#tabSizeHint .

Here is the method that I mentioned: http://doc.trolltech.com/4.5/qtabwidget.html#setTabBar . It is protected, so you will have to inherit QTabWidget and call it from your new c'tor.

first of all, this cant really do much more than segmentation fault:

QTabBar *tabbar=new QTabWidget(this);

QTabBar *tabbar=new QTabWidget(this);

To copy to clipboard, switch view to plain text mode 

you create pointer to QTabBar and make it pointing to QTabWidget...
tell me, what this code does:

QRect rect = tabbar->tabRect(0);

QRect rect = tabbar->tabRect(0);

To copy to clipboard, switch view to plain text mode 

?

If you want to get the tabbar used in QTabWidget, you have to subclass QTabWidget, because tabBar() and setTabBar() are protected methods.

hi,
this is typing mistake here
I used

QTabBar *tabbar=new QTabBar(this);

QTabBar *tabbar=new QTabBar(this);

To copy to clipboard, switch view to plain text mode 

I want to change the size of Tabs in TabBar ...What to do to change it.
thnx

Inherit QTabBar, e.g.

class MyTabBar : public QTabBar { ... };

class MyTabBar : public QTabBar { ... };

To copy to clipboard, switch view to plain text mode 

Re-implement the tabSizeHint function http://doc.trolltech.com/4.5/qtabbar.html#tabSizeHint .

Inherit QTabWidget:

class MyTabWidget : public QTabWidget { ... };

class MyTabWidget : public QTabWidget { ... };

To copy to clipboard, switch view to plain text mode 

In your constructor, call setTabbar( ) and make it use MyTabBar.

i used tabSizeHint () in MyTabBar class inherited from QTabBar class.

class MyTabBar:public QTabBar
{
   public:
    MyTabBar(QWidget *parent):QTabBar(parent)
    {
QIcon callIcon(":/images/a.png");
this->addTab(callIcon," ");
QSize size=this->tabSizeHint(1);
this->setIconSize(size);
 
    }
};

class MyTabBar:public QTabBar
{
   public:
    MyTabBar(QWidget *parent):QTabBar(parent)
    {
QIcon callIcon(":/images/a.png");
this->addTab(callIcon," ");
QSize size=this->tabSizeHint(1);
this->setIconSize(size);

    }
};

To copy to clipboard, switch view to plain text mode 

but i didn't get wat u mean by reimplementing tabsizehint()??
