Description Florian 2012-04-23 11:53:34 UTC 
I added a note item to my Use Case diagram. I have set the text to "Opt-in?", but in order to make the text visible, I had to resize (widen) the note. After clicking printing/print preview, Umbrello resets the size of all note items to the default size and thus the text is not visible anymore.

Reproducible: Always

Steps to Reproduce:
1. Add a Note item to a Use Case diagram
2. Change text to "Opt-in?" (or anything else)
3. Resize the Note item until text is visible
4. Open print preview
Actual Results:  
Note items are resized to default size, text is not visible.

Expected Results:  
Do not change size of a Note item, in order to keep the text visible in printouts

Same issue with Box items, too.
Comment 3 Ralf Habacker 2012-05-30 11:52:32 UTC 
The problem is caused by the implementation of UMLWidget::updateComponentSize(), which casts the widget size to the minimum size of the widget. 

This is the related call stack: 
umbrello.exe!UMLWidget::updateComponentSize()  Zeile 1298	C++
umbrello.exe!UMLWidget::forceUpdateFontMetrics(QPainter * painter)  Zeile 1447	C++
umbrello.exe!UMLScene::forceUpdateWidgetFontMetrics(QPainter * painter)  Zeile 3885	C++
umbrello.exe!UMLScene::print(QPrinter * pPrinter, QPainter & pPainter)  Zeile 516	C++
umbrello.exe!UMLDoc::print(QPrinter * pPrinter, DiagramPrintPage * selectPage)  Zeile 2570	C++
umbrello.exe!UMLApp::slotPrintPreviewPaintRequested(QPrinter * printer)  Zeile 1323	C++

I changed the implementation of updateComponentSize() to 
/**
 * Update the size of this widget.
 */
void UMLWidget::updateComponentSize()
{
    if (m_doc->loading())
        return;
-    QSize size = minimumSize();
-    setSize(size.width(), size.height());
+   clipSize();
    adjustAssocs(x(), y());    // adjust assoc lines
}

which is a workaround for this issue.

Further digging shows the real problem which is located in minimumSize():

UMLSceneSize NoteWidget::minimumSize()
{
    int width = 60;
    int height = 30;
       if (....)
       ...    
      else {
        // keep width and height unchanged
    }
    return UMLSceneSize(width, height);
}

For default notes the size is mapped to hardcoded values instead of leaving unchanged as indicated by the comment.
