Hi all,

I am trying to design a user interface with Python, based on hildon and gtk GUI packages of the Maemo 5 OS.
I would like to design a dialog with elements contained in a scrollable area, but I did not yet manage to achieve my purpose.
An existing example of a scrollable dialog can be found in the calendar app of the Maemo 5 OS. When creating or updating an "event", a dialog is displayed with a scrollable area where the date and hour of the event can be set, with the name and the place of the event, et caetera... You should be familiar with this dialog, aren't you?

What I did (without success) was:
- the creation of a dialog (gtk.Dialog),
- the assignment of a pannable area to the vbox of the dialog
- the addition of all GUI elements to this pannable area instead of the dialog's vbox

With this, nothing is displayed in the dialog. Please find a snippet of my code below.
Code:
import urllib
import urllib2
import gtk
import hildon

class MyDialog(gtk.Dialog):
    def __init__(self,parent):
        # Init of the dialog with an OK button
        gtk.Dialog.__init__(self,'Title',parent,gtk.DIALOG_MODAL,(gtk.STOCK_OK, gtk.RESPONSE_ACCEPT))
        # Init of a pannable area
        pann = hildon.PannableArea()
        # add it to the dialog vbox
        self.vbox.add(pann)

        # insertion of a picker button
        self.pb1 = hildon.PickerButton(gtk.HILDON_SIZE_FINGER_HEIGHT,hildon.BUTTON_ARRANGEMENT_VERTICAL)
        self.pb1.set_title('PButton 1')
        self.pb1.show()
        pann.add_with_viewport(self.pb1)
        # init of the selector of this Picker Button
        self.pb1_sel = hildon.TouchSelector(text = True)
        self.pb1_sel.append_text('Elt 1')
        self.pb1_sel.append_text('Elt 2')
        self.pb1_sel.append_text('Elt 3')
        self.pb1.set_selector(self.pb1_sel)
        
        # insertion of an input field
        self.input1 = hildon.Entry(gtk.HILDON_SIZE_AUTO)
        self.input1.show()
        pann.add_with_viewport(self.input1)
        
        # insertion of a picker button
        self.pb2 = hildon.PickerButton(gtk.HILDON_SIZE_FINGER_HEIGHT,hildon.BUTTON_ARRANGEMENT_VERTICAL)
        self.pb2.set_title('Title 2')
        self.pb2.show()
        pann.add_with_viewport(self.pb2)
        # init of the selector of this Picker Button
        self.pb2_sel = hildon.TouchSelector(text = True)
        self.pb2_sel.append_text('Elt 1')
        self.pb2_sel.append_text('Elt 2')
        self.pb2_sel.append_text('Elt 3')
        self.pb2.set_selector(self.pb2_sel)
        
        # insertion of an input field
        self.input2 = hildon.Entry(gtk.HILDON_SIZE_AUTO)
        self.input2.show()
        pann.add_with_viewport(self.input2)
        

        # insertion of a picker button
        self.pb3 = hildon.PickerButton(gtk.HILDON_SIZE_FINGER_HEIGHT,hildon.BUTTON_ARRANGEMENT_VERTICAL)
        self.pb3.set_title('Title 3')
        self.pb3.show()
        pann.add_with_viewport(self.pb3)
        # init of the selector of this Picker Button
        self.pb3_sel = hildon.TouchSelector(text = True)
        self.pb3_sel.append_text('Elt 1')
        self.pb3_sel.append_text('Elt 2')
        self.pb3_sel.append_text('Elt 3')
        self.pb3.set_selector(self.pb3_sel)
        
        # insertion of a picker button
        self.pb4 = hildon.PickerButton(gtk.HILDON_SIZE_FINGER_HEIGHT,hildon.BUTTON_ARRANGEMENT_VERTICAL)
        self.pb4.set_title('Title 4')
        self.pb4.show()
        pann.add_with_viewport(self.pb4)
        # init of the selector of this Picker Button
        self.pb4_sel = hildon.TouchSelector(text = True)
        self.pb4_sel.append_text('Elt 1')
        self.pb4_sel.append_text('Elt 2')
        self.pb4_sel.append_text('Elt 3')
        self.pb4.set_selector(self.pb4_sel)
        

        # insertion of a picker button
        self.pb5 = hildon.PickerButton(gtk.HILDON_SIZE_FINGER_HEIGHT,hildon.BUTTON_ARRANGEMENT_VERTICAL)
        self.pb5.set_title('Title 5')
        self.pb5.show()
        pann.add_with_viewport(self.pb5)
        # init of the selector of this Picker Button
        self.pb5_sel = hildon.TouchSelector(text = True)
        self.pb5_sel.append_text('Elt 1')
        self.pb5_sel.append_text('Elt 2')
        self.pb5.set_selector(self.pb5_sel)
        

# display of the dialog
dialog = MyDialog(None)
res = dialog.run()
dialog.destroy()
If I don't use a PannableArea, and I pack_start() all the elements to the vbox, I don't get enough space and the elements are smaller than expected.

Can you help me please?


Kind regards

Don't put more than one widget in the pannable area.
Use another vbox to put there your buttons and textfield, and
put this vbox in the pannable area.
Call pan.show_all() afterwards. You have to set the default size
for the dialog, otherwise the automatic height is too small.
(I don't know if there is another way than calling set_default_size.)

Vielen danke Nicolai!

In fact that is what I did:
- as I forgot to show() my pan, I added the instruction;
- I also added a vbox to the pan;
- and I resized the dialog which was too small, but with the self.set_size_request() method.

Thanks a lot!
Kind regards
