How to write coding for the selected item in the QListWidget?

[harish]

Hi all,
I am having a QListwidget which contains some items in it.

Now what i am trying for is:When i click anyone of those items in the list it should display some information about it.
Here is the code of mine:


void MainWindow:n_pushButton_clicked()
{

QListWidget *listWidget = new QListWidget();

listWidget->addItem(new QListWidgetItem("A"));
listWidget->addItem(new QListWidgetItem("B"));
listWidget->addItem(new QListWidgetItem("C"));
listWidget->addItem(new QListWidgetItem("D"));
listWidget->addItem(new QListWidgetItem("E"));
listWidget->addItem(new QListWidgetItem("F"));
listWidget->addItem(new QListWidgetItem("G"));
listWidget->setStyleSheet("* { background-color:black; padding: 7px ; color: white}");

listWidget->setStyleSheet( " QListWidget::item:selected:active {background: qlineargradient(x1: 0, y1: 0, stop: 0 red);}");

listWidget->showFullScreen();

}



If i click A-it should display something about "A" and for each and every item.


Is there any code of property so that i can finish my work.


Anyone help me with this.

Thanks and Regards,
Harish.M

Now what i am trying for is:When i click anyone of those items in the list it should display some information about it.

What is 'it'?? The list widget? The list widget should display more information?

I need to display a QMessageBox?

It should display some text in a QMessageBox when any item in the list is selected....

Connect the itemClicked() or currentItemChanged() signal of the list widget to a slot that display the message box. Both slots provide a way to access the data of the clicked item.

Thank you Chris it got worked..

Thank you once again.

Now i am trying to display different messages in a QMessageBox when selecting each item.

Suppose if select "A" it should display A for APPLE and if "B" is selected it displays B for BANANA...

How to add this property in this?

[ChrisW67]

The clicked item is passed in to the slot. You can look at which item it is and make decision about what to display.

Hi, Am a newbie to qt and require some guidance from you guys.
How to place the selected item to center in a qlistwidget ?.
Assume that there are 10 items in a qlistwidget and only 5 index values are visible at a time. If I select the fourth index value or item, how could i scroll the selected item to the 2nd index and view the next items from the fourth index.

Is there any way to do this?

Thanks ... :)
