    Default Re: Add Items to QListView

    Hi,

    I am a complete beginner to Qt. Please pardon my stupid question!

    I found many threads and examples related to this but still I am unable to clear it out. I have a listView created by Qt Creator. And I want to add items to the list just like the one figure I am attaching here. Every row consists of one small icon and a text label.

    How do I do that ?

    Any help would be appreciated.

    Thanks

    Hey Man,

    I am not the best at C++ but this is how I would go about it...

    Firstly, create a class for each of your QListItem's by using the following:
    Qt Code:
    1. class MyListItem : QListWidgetItem
    2. {
    3. public:
    4. QPixmap *icon_to_be_shown;
    5. };
    To copy to clipboard, switch view to plain text mode 

    Now you will want to create the QListWidget itself and also create your actual item:
    Qt Code:
    1. void Main()
    2. {
    3. //Create Our QListWidget
    4. QListWidget *mylist = new QListWidget;
    5.  
    6. //Create Our Item
    7. MyListItem *itm = new MyListItem;
    8. itm->setText("My Item");
    9. itm->icon_to_be_shown = "PATH TO PICTURE";
    10.  
    11. //Add Our Item To Our List
    12. mylist->addItem(itm);
    13. }
    To copy to clipboard, switch view to plain text mode 

    Hope this bit of code helps man, also you should look into QListWidget as oppose to QList =)

    no need to subclass QListWidgetItem.


    Please note the difference between QListWIDGET and QListVIEW! Check the docs to see which one you require.
    If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.

    for starters, you should ask yourself how Qt would know what to do with your 'pointer = string literal'? Your solution won't do anything, even if it would compile... How does the list magically know about this pixmap pointer that you have added?

    Qt Code:
    1. QPixmap *icon_to_be_shown;
    2. icon_to_be_shown = "PATH TO PICTURE";
    To copy to clipboard, switch view to plain text mode 
    That doesn't make sense at all.

    The docs are, as per usual, useful:
    http://doc.qt.io/qt-4.8/qlistwidgetitem.html#setIcon
