Fixed in commit 877b93c

Tables can now be edited from inside an InputDialog. See the following example
giving the following output after changing the entries in the first column to '1'.


  • You have to use the itemtype='widget' syntax to get the results of the table back in the dialog results.
  • The result is an array for the ArrayModel, and a list for

the TableModel.

  • TableModel can have per row or per column different type.
  • Default TableModel type is str.
  • The possibility of adding a plain widget to the dialog items

is intended for widgets that just display information or that aid in the working of other input fields. They can not return a value, as they do not even have a key (name).

I leave this bug open for a while, in case some problems arise with the new functionality.

For the nested results: consider this example:

def run2():
"""Table widget in InputDialog"""
dataTable = np.arange(40).reshape((-1, 2)).tolist()
# print(dataTable)
table = widgets.Table(dataTable, label='table',chead=[1, 2], edit=True)

input_data = [
dict(name='bla',value=None,text="A constant info field",itemtype='info'),
_I('clist',['First','Third'],text="itemtype 'list' with check=True",itemtype='list',choices=['First','Second','Third','Fourth'],check=True),
dialog = widgets.InputDialog(input_data, autoprefix=True,caption='InputDialog',modal=True)
print dialog.getResult()
print table.tm.arraydata

The getResults() will only output [('bla', None), ('clist', ['First', 'Third'])], while we also want the table.tm.arraydata in the results I imagine!

I have not found a way to fix this without breaking something else.

We need to revive this bug, or close it.

I am not sure I understand the problem with the nested results.

As far as Array/Table model is concerned: I suggest Array to be used for float/int tables, while Table holds just strings.
We could add a list of validator and/or convertor functions though, permitting the table to have different type of values in different columns.

The ArrayModel could rely on the data being a numpy array, and thus could also use numpy methods and access elements as data[row,column].

The TableModel will always us a list of lists and elements are accessed as data[row][column]. This model could allow rows of unequal length.

Fixed the "array" problem.
It seems two different functions are called depending on the type of list/array:


But I don't really see the point of this.

Still to do:
getResults to show nested widget results.

Fixed it so now you can edit tables.
Array->list can be fixed easily by IF statement and tolist, but thinking of other way.

New bug found: InputDialog > getResults will only show the results of the 'items' i.e. the dictionaries added, not the results of the nested Widgets.
Quick fix: ask directly for result of nested Widget, e.g.:
table.tm.arraydata , but thinking of a way to make it general for all widgets.

Editing a Table widget has not been implemented yet. Still I consider it important, so I have added an entry for this in the Tasks list. Now we are just waiting for somebody to pick it up ;)

Table widget can't display numpy arrays. Data have to be converted into List.

Editing the table through the interface (parameter edit=True) doesn't work.
