Combobox in TTkTable

[lucaminifreelance-art]

Hi,
can you suggest me the best wayt to use a combobox in certain column cells (or single cells) of a table?
Thx in advance
Luca

unfortunately the table does not supports widgets the same way the tree does (you cannot place a widget in the table), but you can create a custom data type which will open a combobox when edited (doubleclick or space when selected)
if this is ok for you I can make a prototype.

[lucaminifreelance-art]

It seems like a good idea but I'm not sure I fully understand what you're proposing to do...so, yes, please.

[ceccopierangiolieugenio]

hi, sorry for the late reply, I am haveing some busy days and I cannot provide you yet an examplem for this, I think I need to rework a little bit the table engine to make it easier to enable custom widgets.

[lucaminifreelance-art]

no problem...do it when you can... :)
Thanks in advance

Is it something like this you are looking for?

I made a demo but I need to refine it and add few more use cases,
Anyway I am thinking to add a new type in the table to address this.

[lucaminifreelance-art]

yes, it is exactly what I need!

Finally I added support for lists and booleans in #546

just pull the latest with:

pip install --upgrade git+https://github.com/ceccopierangiolieugenio/pyTermTk.git#subdirectory=libs/pyTermTk

and run test.ui.032.table.15.list.item.py

python tests/t.ui/test.ui.032.table.15.list.item.py

(purtroppo un trasloco e una restrutturazione allungano i tempi1)

I understand...Anyway this is a great news! Thank you.
A little question: I've seen boolean have a representation with ('True','False') strings. If I would like to change it to ('Yes','No'), how I can do it?

[slook]

You can do it if you order it in the other way around like ['No', 'Yes'] and then get the currentIndex() the first "No" item will be 0 (i.e. 'False') and the second "Yes" item will be at index 1 (i.e. True).

[ceccopierangiolieugenio]

The easiest thing right now is to use a list ('yes','no'), unfortunately it is not possible to subclass the boolean, it would have been very handy. But I can check if I can extend it with enum, so you can define an Enum and have an option for it, that would be interesting.

[slook]

It is quite common to want a "human name" string for a setting identifier in the data field such as in a TTkList that contains a list of TTkAbstractListItem("Human Name", data="internal_name")s so it would be good to either make the TTkCombobox widget capable of spawning a TTkList or an array of TTKAbstractListItem in the same way like the TTkListWidget does via emitting a signal called itemClicked.

Added enum support here #548

You can define a custom enum and use it in the table:

class MyEnum(Enum):
    Foo=auto()
    Bar=auto()
    Baz=auto()

    def __str__(self):
        return self.name

class MyEnumYesNo(Enum):
    Yes=True
    No=False

    def __str__(self):
        return self.name
    def __bool__(self):
        return self.value

you can have a look at this example:
