Hello everybody, I try to use Pmw library -> ScrollListBox. If I take the example of the reference web site (see below, I just quote the minimal code to launch, I note by <----- the line which are not execute when I click) It works, except selectioncommand and dblclickcommand: associate function doesn't run when I click one or two time. Could you have an idea about that ? Is it about my tried code ?
Thank, Guilhem from Tkinter import * import Pmw #from pymol import * class Demo: def __init__(self): parent=Tk() Pmw.initialise(parent) # Create the ScrolledListBox. self.box = Pmw.ScrolledListBox(parent, items=('Sydney', 'Melbourne', 'Brisbane'), labelpos='nw', label_text='Cities', listbox_height = 6, selectioncommand=self.selectionCommand, dblclickcommand=self.defCmd, usehullsize = 1, hull_width = 200, hull_height = 200, ) # Create a group widget to contain the scrollmode options. w = Pmw.Group(parent, tag_text='Scroll mode') w.pack(side = 'bottom', padx = 5, pady = 5) hmode = Pmw.OptionMenu(w.interior(), labelpos = 'w', label_text = 'Horizontal:', items = ['none', 'static', 'dynamic'], command = self.sethscrollmode, menubutton_width = 8, ) hmode.pack(side = 'top', padx = 5, pady = 5) hmode.invoke('dynamic') vmode = Pmw.OptionMenu(w.interior(), labelpos = 'w', label_text = 'Vertical:', items = ['none', 'static', 'dynamic'], command = self.setvscrollmode, menubutton_width = 8, ) vmode.pack(side = 'top', padx = 5, pady = 5) vmode.invoke('dynamic') buttonBox = Pmw.ButtonBox(parent) buttonBox.pack(side = 'bottom') buttonBox.add('yview', text = 'Show\nyview', command = self.showYView) buttonBox.add('scroll', text = 'Page\ndown', command = self.pageDown) buttonBox.add('center', text = 'Center', command = self.centerPage) # Pack this last so that the buttons do not get shrunk when # the window is resized. self.box.pack(fill = 'both', expand = 1, padx = 5, pady = 5) # Do this after packing the scrolled list box, so that the # window does not resize as soon as it appears (because # alignlabels has to do an update_idletasks).
