I _think_ I have code that does waht you want. This creates multiple
layouts that contain an icon, a button, and some text on a scrollview.
The code is awkward and ugly, but it works.
class ScrollToolView(QScrollView):
def __init__(self,parent = None,name = None,fl = 0):
QScrollView.__init__(self,parent,name,fl)
self.items = {}
self.setStaticBackground(True)
self.enableClipper(True)
self.viewport().setPaletteBackgroundColor(qApp.palette().color(QPalette.Active,
QColorGroup.Background))
self.row_height = 120
def viewportResizeEvent(self, e):
for x in self.items:
self.items[x].resize(e.size().width(), self.row_height)
def addItem(self, name, title, pix, text, button_text, button_func):
num_items = len(self.items)
LayoutWidget = QWidget(self.viewport(),"layoutwidget")
LayoutWidget.setSizePolicy(QSizePolicy(QSizePolicy.Expanding,
QSizePolicy.Minimum))
LayoutWidget.setGeometry(QRect(0, 0, self.width(),
self.row_height))
self.addChild(LayoutWidget)
if num_items:
self.moveChild(LayoutWidget, 0, self.row_height*num_items)
layout = QGridLayout(LayoutWidget,1,1,10,10,"layout")
pushButton = QPushButton(LayoutWidget,"pushButton")
pushButton.setSizePolicy(QSizePolicy(QSizePolicy.Maximum,QSizePolicy.Fixed,0,0,
pushButton.sizePolicy().hasHeightForWidth()))
self.connect(pushButton,SIGNAL("clicked()"), button_func)
layout.addWidget(pushButton,2,2)
textLabel = QLabel(LayoutWidget,"textLabel")
layout.addWidget(textLabel,1,1)
pixmap = QLabel(LayoutWidget,"pixmapLabel2")
pixmap.setSizePolicy(QSizePolicy(QSizePolicy.Fixed,QSizePolicy.Fixed,0,0,
pixmap.sizePolicy().hasHeightForWidth()))
pixmap.setMinimumSize(QSize(32,32))
pixmap.setMaximumSize(QSize(32,32))
pixmap.setPixmap(pix)
pixmap.setScaledContents(1)
layout.addWidget(pixmap,1,0)
textLabel2 = QLabel(LayoutWidget,"textLabel2")
textLabel2.setAlignment(QLabel.WordBreak | QLabel.AlignTop)
textLabel2.setSizePolicy(QSizePolicy(QSizePolicy.Minimum,QSizePolicy.Expanding))
layout.addWidget(textLabel2,2,1)
if num_items:
line = QFrame(LayoutWidget,"line")
line.setFrameShadow(QFrame.Sunken)
line.setFrameShape(QFrame.HLine)
layout.addMultiCellWidget(line,0,0,0,2)
textLabel.setText(title)
textLabel2.setText(text)
pushButton.setText(button_text)
self.resizeContents(self.width(), num_items*self.row_height*2)
LayoutWidget.show()
try:
self.items[name]
except KeyError:
self.items[name] = LayoutWidget
else:
print "ERROR: Duplicate button name:", name
def clear(self):
if len(self.items):
for x in self.items:
self.removeChild(self.items[x])
self.items[x].hide()
self.items.clear()
self.resizeContents(self.width(), 0)
