Currently the power of uitable and uitree is very limited.
Which features are missing to improve the usability of your GUIs?
No products are associated with this question.
It would be nice to be able to update the contents of a single uitable cell without "flicker". As it stands now, it is easy to modify the 'String' property of a uicontrol, call a drawnow(), and have it immediately update without flicker. To do the same in a uitable, you have to update the entire 'Data' cell array for all cells, causing flicker on the refresh. Also, when this occurs, the uitable scrolls back to its top-most position, which is confusing and distracting for the user.
Some further ideas:
All these features are available in the Java-level, but Yair's findjobj needs more than a second to locate the handle and there is no guarantee, that it works in future versions also. See Undocumented: uitree. It would be much smarter if these important objects can be accessed from Matlab exhaustively and with documentation as well as support.
uicontrol('Style','edit') and uitable cells should support a "PICTURE" input validation field; the field could be a string containing a % format, or a string containing a regex, or the handle of a routine. The validation would be "live", as characters are typed, with user notification (e.g. a beep, with provision made for visual notification for the deaf) as soon as they enter the wrong character.
drag-and-drop. Extended cut-and-paste (e.g., blocks of table)
Ability to find out which uitable cells are visible, and ability to set the scrollbars so that a particular part is visible.
Embedded 'vi' editor mode.
I'd like to have an additional Property 'RowEditable' similar to the property 'ColumnEditable'. Both properties should work at the same time such that the user is only allowed to change certain submatrices of the entire table.
Other things I'd like to have:
Concerning uitree: This function is not even a supported function. It would be extremely nice to have an "official" uitree function in MATLAB.
puting the cursor in specific cell of uitable in the matlab is not provided.This is really important of disp and controling the data in uitable.
Having a button up/ button down callback, or some way of determining whether the user is selecting single or multiple cells would be really useful.
