Setting an icon to an Item in a QlistWidget

[LordQt]

Hello friends,

How can i set an icon to an Item in my Qlistwidget my code is like this:


QDockWidget *dock = new QDockWidget(tr("Verwaltung"), this);
QFont font("Verdana", 10, QFont::Bold);
dock->setFont(font);
//set the color of the dockwidget
dock->setAutoFillBackground(true);
QPalette qpal;
qpal.setColor(QPalette::Active,QPalette::Window,QC olor(210,239,109));
dock->setBackgroundRole(QPalette::Window);
dock->setPalette(qpal);
//end set color
dock->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);
customerList = new QListWidget(dock);
customerList->addItems(QStringList("Bezirksverwaltung"));

If you have a QStringList you want to add to the view:


QIcon icon=...
foreach(QString str, myStringList) {
QListWidgetItem *item = new QListWidgetItem(icon, str, customerList);
customerList->addItem(item);
}


EDIT:
Actually, you don't have to use addItem when you pass the list widget as parent in the list widget item's constructor.

Hello thanks but some problems occures:


customerList = new QListWidget(dock);
QIcon icon=new QIcon(":/images/labelic1.ico");
foreach(QString str, myStringList) {
QListWidgetItem *item = new QListWidgetItem(icon, str, customerList);
customerList->addItem(item);

what is str and customerList?

[marcel]

what is str and customerList?
Funny you ask :).
customerList is your QListWidget.
str is a QString and it represents the text you want your item to display(besides the icon).

EDIT: and myStringList is a QStringList containing the strings of the items you want to add( f.e. the names of the customers)

;o)) i meant myStrList.....

so I have some code:



QDockWidget *dock = new QDockWidget(tr("Verwaltung"), this);
QFont font("Verdana", 10, QFont::Bold);
dock->setFont(font);
//set the color of the dockwidget
dock->setAutoFillBackground(true);
QPalette qpal;
qpal.setColor(QPalette::Active,QPalette::Window,QC olor(210,239,109));
dock->setBackgroundRole(QPalette::Window);
dock->setPalette(qpal);
//end set color
dock->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);
customerList = new QListWidget(dock);
QStringList myStringList("hallo","servus");
QIcon *icon=new QIcon(":/images/labelic1.ico");
foreach(QString str, myStringList) {
QListWidgetItem *item = new QListWidgetItem(icon, str, customerList);
customerList->addItem(item);
}
dock->setWidget(customerList);
addDockWidget(Qt::LeftDockWidgetArea, dock);
viewMenu->addAction(dock->toggleViewAction());


But iI get some Errors like this:

[marcel]

QStringList myStringList;
myStringList << "item1" << "item2" << "item3"; //and so on...

[LordQt]

Ok



QStringList myStringList;
myStringList <<"Bezirksverwaltung" << "FAkturierung";
QIcon *icon=new QIcon(":/images/labelic1.ico");
foreach(QString str, myStringList) {
QListWidgetItem *item = new QListWidgetItem(icon, str, customerList);
customerList->addItem(item);


I have always one error :

It is:


QListWidgetItem *item = new QListWidgetItem(*icon, str, customerList);

because you create the QIcon on the heap. It is a pointer. The constructor takes as parameter a const reference to a QIcon, not a pointer.

Regards

[LordQt]

And how can i create my QIcon in a right way??

like this Qicon *icon; icon=("......");

or like this QIcon *icon("....."); ????

[marcel]

Like this:


QIcon icon(":/images/labelic1.ico");

[LordQt]

Ok i hope i Dónt mess up your nervs with my question but i am new to qt.
your code compiles atm without errors but i can´t see my icon have you an idea??

[marcel]

Probably you didn't compiled the resource file or it is not correct. Can you post it?

Regards

[LordQt]

Ok

And I add a Screenshot from my App!

[LordQt]

and this is my Resource:



<!DOCTYPE RCC><RCC version="1.0">
<qresource>
<file>images/new.png</file>
<file>images/print.png</file>
<file>images/save.png</file>
<file>images/undo.png</file>
<file>images/Modestsplash.png</file>
<file>images/labelic1.ico</file>
</qresource>
</RCC>

[marcel]

Add RESOURCES = yourresource.qrc to the pro file( or run qmake -project again).

Make sure you replace the qrc name with the appropriate one.

[LordQt]

hmmmm the resources += is on top and the name is correct but nothing seems to change i don´t see my icon ????And i compile it again

[marcel]

Is then the relative path correct?
Judging from the path the images directory should be in the same dir with the qrc file.

Regards

[LordQt]

My icon is in the images folder the pro file one level higher or what du you mean?

[LordQt]

Hello i solve it!!

my icon is corrupt i take a png format and it runs. But by this way the code is written by automatic appending the icon to the item. But right now i have one icon for each item in my dockwidget. How can i put seperate icon to each item??
