    Default ListWidget -> custom Item -> height

    So mine question is: is there any way to make listWidgetItem occupy as much space as it needs (apposed to fixed size)? I use customised widget as items (2 labels + picture + Multi-line lable).

    You have to compute tha maximum size hint of single components.

    Well.. the maximum size of hints is the same... I tried to compine their heights using, for example:
    name = new QLabel("Name");
    int asd;
    asd += int->height();
    but all the labels have the same height, so i cannot define which items should be bigger, and which should be smaller...

    The size hint is computed by widget and depends on their content.

    This code works
    Qt Code:
    1. void Widget::on_computeButton_clicked()
    2. {
    3. int maximumSizeHint = 0;
    4.  
    5. QList<QLabel*> labels = this->findChildren <QLabel*> ();
    6. Q_FOREACH (QLabel* lab, labels) {
    7. int itemp = lab->sizeHint ().height ();
    8.  
    9. qDebug ("%s sizeHint.height = %d", qPrintable(lab->objectName ()), itemp);
    10. if (itemp > maximumSizeHint)
    11. maximumSizeHint = itemp;
    12. }
    13.  
    14. qDebug ("Maximum sizeHint height = %d", maximumSizeHint);
    15. }
    To copy to clipboard, switch view to plain text mode 

    The output is:
    Qt Code:
    1. label sizeHint.height = 13
    2. label_2 sizeHint.height = 13
    3. label_3 sizeHint.height = 39
    4. Maximum sizeHint height = 39
    To copy to clipboard, switch view to plain text mode 

    The widget is in attachment:image.PNG
