Create a custom slot and connect it to:
void QTreeWidget::itemClicked(QTreeWidgetItem* item, int column) [signal]

In the slot, use QDesktopServices (new in Qt 4.2) to open the URL.

Btw, how is this related to Qt Designer?

[sunil.thaha]

To add to that

When you add items to the Tree. Have the items associatd to an Url using
QTreeViewItem::setData function

On item clicked you can retreive the url and use QDesktopServices or QTextBrowser for the display

[e8johan]

Connect a slot showing the page to the QAbstractItemView::clicked ( const QModelIndex & index ) signal from your TreeView/Widget.

i had checked already not even giving error but these are not working
coding s like

void form1::showResult(QTreeWidgetItem * item, int column)
{
QString str,str1;
str=item->text(0);

if(str.compare("sub11")==0)

{
QUrl url("http://www.google.com");
}

its not working on selected event of sub11

Are you using Qt 4.2? Did you read about QDesktopServices which was already suggested in earlier posts?

If you are using an earlier version of Qt, try searching the forums. This subject has been discussed several times, like for example in this thread (http://www.qtcentre.org/forum/f-qt-programming-2/t-qt41how-to-make-links-open-browsers-233.html).

QUrl url("http://www.google.com");
== snip ==
so plz suggest me for coding in "if " part

I suggest you take a look at QUrl docs and read what the class is meant to do. Trying random classes won't help you much...



str.compare("sub11")==0
And what is this? How about:
if(str=="sub11") ...?

[jyoti]

i m using qt4.2 designer....(ui is attached) on MAC OS


if(str1=='sub1') is equally same as i mentioned wid compare..

n again asking problem is
when i click to 'sub1'
then a page"google.com" should be opened in textbrowser
plz suggest its coding
my mail address jyoti.verma@stellarinfo.com

[wysota]

QDesktopServices::openUrl().

[jyoti]

my coding part:


void form1::showResult(QTreeWidgetItem * item, int column)
{
QString str,str1;
str=item->text(0);

if(str.compare("sub1")==0)

{
QUrl myurl;
myurl=QUrl::fromEncoded("http://www.google.com");
textBrowser->setSource(myurl);

}

form1 is my name of form

so plz suggest me best fit coding
as u say QDesktopServices::
as i find openURl() take bool value...

[wysota]

as i find openURl() take bool value...
?????????????????????????????

AFAIK this method takes a QUrl argument...


QDesktopServices::openUrl(QUrl("http://www.qtcentre.org"));

[jyoti]

thank u very much...:)


but can u plz help me abt this type of another query...
if my file is placed on my desktop n i want the same...
means on selection of "sub11"
a help folder should be opened..which is placed on my desktop...

plz do help me out....as soon as possible

thanks in advance

[wysota]

Just change the URL to point to the file you wish to open. QUrl::fromLocalFile() may be handy.
