Grid binding with other types than "string" or inline-edit with some datetimepicker

Question

So I was trying to add grid binding to an already finished grid that has string and date values. Example: http://www.sencha.com/examples/#ExamplePlace:gridbinding

╔═════════╦═════════════════════╗
║  room   ║      date/time      ║
╠═════════╬═════════════════════╣
║ L1-0056 ║ 25.02.2014 06:23:16 ║
║ L2-0061 ║ 25.02.2014 08:54:31 ║
╚═════════╩═════════════════════╝

Room: ComboBox with room values

Date/Time: Either DatePicker + some self-made TimePicker, or some DateTimePicker library... (getting the gxt-datepicker to work was easy, but I also need to edit the time)

Getting the date values into the editor and vice versa doesn't seem to be the problem (aside from the fact that I also need to edit the time).

There isn't any DateTimePicker in gxt, right? So... how do I define 2 editor fields for one cell in a grid?

Also: using a TextBox to edit the string in the first column works fine, but how can I use a ComboBox as editor?

As an alternative, I used inline-editing: http://www.sencha.com/examples/#ExamplePlace:inlineeditablegrid

In this case, everything works fine. Except the fact, that I still cannot edit the time in the date field with given picker. Not sure what method to pick here (either inline editor or binding) - but on both I cannot figure out how to edit the time-part in the date field, any ideas?

Either one is fine, as long as I get the editing to work.

[edit] the datetime picker part may be answered (thanks :) ), gotta give it a try - any ideas about the combobox-binding?

Answer 1

I would recommend GWT-Bootstrap's DateTimePicker at http://gwtbootstrap.github.io/#component:datetimepicker

It brings up a time picker after the date has been selected:

As you say, there doesn't seem to be an equivalent in GXT.

I'd say you are better off with one widget so if you don't want to use another 3rd-party library then you'll have to roll your own composite widget.
