title : title of the dialog
text : the text to show in the dialog. If text = [text1, text2] text1 will be shown on top
text2 will be shown on the bottom
data : data to show in the dialog. If data is a list, show it in a treeview. otherwise,
show it in a textview.
If treeview, list should be of the type : [[data, value], sensitive]
sensitive : True/False, set the sensitivity of the check button. Default to True
[data, value] : a list of data and it respectives values. Default value are False
exemples : [ [data1, data2], False] : show a treeview with 2 unactivable, unselected row.
[data1, data2] : show a treeview with 2 activable, unselected row.
[[data1, True], [data2, False]] : show a treeview with 2 activable row, the first
selected, the second unselected.
options : list of options to show at the bottom of the dialog.
options should be of the type : [[[option, value]], group]
group : True/False, if True options are grouped and only one could be selected. Default to False
[option, value] : a list of options and their respective values. Default values are False.
See data for an exemple of how it works, it is nearly the same
