Thank you!
I saw dGridSizer too late, when I implemented my Panel subclass for
proper alignment:
class Panel(dabo.ui.dPanel):
"""
Descendant of `dPanel` with simple layout functions.
You might want to access:
:Sizer: main horizontal sizer
:VS: main vertical sizer
"""
def afterInit(self):
super(Panel, self).afterInit()
self.Sizer = dabo.ui.dSizer('horizontal')
self.VS = dabo.ui.dSizer('vertical')
self.VS.DefaultBorder = 5
self.VS.DefaultSpacing = 5
self.Sizer.append(self.VS, proportion=1, layout='normal',
alignment='top')
self.bindEvent(events.Save, self.onSave)
def changeMainSizer(self, **kwargs):
"""
Allow for changing layout properties of main vertical sizer
(`self.VS`).
Parameters: see dSizer.append.

defaults = {
'proportion': 1,
'layout': 'normal',
'alignment': 'top',
}
for k in defaults:
if not k in kwargs:
kwargs[k] = defaults[k]
self.Sizer.remove(self.VS)
self.Sizer.append(self.VS, **kwargs)
def addSpacer(self, proportion=0, size=5):
"""

"""
self.VS.appendSpacer(size, proportion=proportion)
def addVertical(self, object, **kwargs):
"""

kwargs).
"""
if not kwargs:
return self.VS.append1x(object)
else:
return self.VS.append(object, **kwargs)
def addLine(self, widget, **kwargs):
"""

hs = dabo.ui.dSizer('horizontal')
lb = dabo.ui.dLabel(self, Caption=kwargs['Caption'])
hs.append(lb, proportion=4)
hs.append(widget, proportion=10)
hs.appendSpacer(5, proportion=1)
self.VS.append1x(hs)
return widget
def addLabelLine(self, *args, **kwargs):

hs = dabo.ui.dSizer('horizontal')

hs.append(finput, proportion=8)
hs.append(btn, proportion=2)

In my version there are some more additional methods addSomething for
every commonly used widget and some of my own (like FilepathInput with
a getFolder/getFile dialog and some validation) as shortcuts to
self.addLine(someWidget, {}).
