Maurizio (10 days 20 hours ago): Hi Yair, how can I define a callback for a cell/row/column selection? In createTable you can define a data changed callback, but if you simply select a cell, how can you define a...
Donato (12 days 21 hours ago): Hi Yair, it seems that in Matlab R2019b this method doesn’t work. Have you some solutions? Thanks.
Maurizio (14 days 7 hours ago): Thank you Yair, I’ve supposed it, but I was not sure. Maurizio
Yair Altman (14 days 21 hours ago): headers is a simple cell array of strings (column header names). I thought that was pretty obvious from the context… Additional types of uitable customizations are...
Maurizio (14 days 21 hours ago): Hi Yair, i’m trying to use your code example to change the colors of a table cell, but I have a doubt: in the following part of your code: % Yellow background for significant...
Mike (17 days 23 hours ago): When I use the suggestion above to set the ‘defaultAxesCreateFcn 217;, it works as expected in that the axes toolbar is gone and the default behavior is to zoom. However,...

Iliya Romm (54 days 5 hours ago): To anybody attempting this in R2019b (and later?): unless you specify the image size, nothing will be shown!. A solution is presented in this answer str = [''];
Yair Altman (58 days 6 hours ago): @Don – you can control the components of controllib.widget.Slider using its internal properties, as follows: >> warning off MATLAB:structOnObject % avoid warning >>...
Don (58 days 8 hours ago): I do not see a visible (on/off) property. Is there a way hide/unhide these, specifically controllib.widget.Slider. I currently just use Position and move it out of visible range. Also,...
Philip Howard (65 days 1 hour ago): Yair, Thank you for your post. Is it possible to use Matlab functions inside the SQL query for method using sqlite-jdbc? I see here that you can create custom callback...
Yair Altman (73 days 6 hours ago): The default Java Look&Feel for UI buttons paints the border together with the contents, and apparently prevents changing both of them together (reference). Changing to a...
Jacob (73 days 16 hours ago): So, I’m having trouble finding information on this. If I change the border of a button, then change the background color, the border resets. Then I am not able to change the...
