In general smartphone programming is slightly different from programming for a standard Pocket PC device. As you mentioned the first issue you typically come across is the lack of ability to select a control. The solution to this is to programatically select the first control on your window when initialising it. The OS has support within the default window procedure to then allow the user to "tab" between controls when the up or down arrow keys are pressed. A potentially larger problem with TKinter (a toolkit that I have no experience with) are issues around the standard controls such as combo boxes and buttons. On a Windows Mobile smartphone standard controls such as a combo box are exactly the same as you would see on a Pocket PC device. This leads to usability problems, for instance with a combo box there is no way to drop down it's list without being able to click on the little arrow button to the side of the control, which you obviously can't do on most smartphones. For this reason Microsoft suggests using a series of alternative controls. For example what you may think is a combo box within a smartphone application is probably a 1 line high listbox coupled with an up/down spinbox auto-buddy docked to its right. Application frameworks such as the .NET Compact Framework generally abstract this different within their control classes, so an application programmer creates a "combobox" and the framework determines which set of native controls need creation to implement this. I assume that TKinter probably hasn't been implemented with this kind of thing in mind. Hope this helps, Christopher Fairbairn PS: Just thinking about it now I bieleve TKinter is a framework which essentially draws all it's own custom controls. If this is the case the problem is probably more involved, since you won't get the native OS support for selecting controls on a smartphone etc. _______________________________________________ PythonCE mailing list PythonCE@python.org http://mail.python.org/mailman/listinfo/pythonce
