Clicking a button or moving a scroller will cause the callback to be executed. Also, pressing enter in a text box causes the callback to be executed. - cdata - an M x N x 3 array that represents an RGB image to use as the truecolor image displayed on push bottons or toggle buttons. The values must be between 0 and 1. - children - Not used. - createfcn - Not used. - deletefcn - Not used; - enable - {'on','inactive','off'} - For on (the default) the uicontrol behaves normally. For inactive, it is not operational, but looks the same as on. For off, the control is grayed out. - extent - a read only property that contains the extent of the text for the control. - fontangle - {'normal','italic','oblique'} - The angle of the fonts used for text labels (e.g., tick labels). - fontsize - scalar - The size of fonts used for text labels (tick labels). - fontunits - Not used. - fontname - string - The name of the font to use for the widget. - fontweight - {'normal','bold','light','demi'} - The weight of the font used - foregroundcolor - colorspec - the foreground color for text. - handlevisibility - Not used. - hittest - Not used. - horizontalalignment - {'left','center','right} - determines the justification of text. - interruptible - Not used. - keypressfcn - functionspec - a string or function handle that is called when a key is pressed and a uicontrol object has focus. - listboxtop - a scalar (used only by the listbox style of uicontrols) that specifies which string appears at the top of the list box. - max - a scalar that specifies the largest value allowed for the value property. The interpretation varies depending on the type of the control \begin{itemize} - check boxes - specifies what value is set to when the check box is selected. - edit box - if max-min>1 then the text box allows for multiple lines of input. Otherwise, it is a single line only. - list box - if max-min>1 then multiple item selections are allowed. Otherwise, only single item selections are allowed. - radio buttons - specifies what value is set to when the radio button is selected. - slider - the maximum value the slider can take. - toggle button - specifies what value is set to when the toggle button is selected. \item min - a scalar that specifies the smallest value for the value property. The interpretation of it depends on the type of the control - check boxes - specifies what value is set to when the check box is not selected. - edit box - if max-min>1 then the text box allows for multiple lines of input. Otherwise, it is a single line only. - list box - if max-min>1 then multiple item selections are allowed. Otherwise, only single item selections are allowed. - radio buttons - specifies what value is set to when the radio button is not selected. - slider - the minimum value the slider can take. - toggle button - specifies what value is set to when the toggle button is not selected. \item parent - the handle of the parent object. \item position - size and location of the uicontrol as a four vector [left, bottom, width, height]. If width>height then sliders are horizontal, otherwise the slider is oriented vertically. \item selected - {'on','off'} - not used. \item selectionhighlight - {'on','off'} - not used. \item sliderstep - a two vector [min_step max_step] that controls the amount the slider value changes when you click the mouse on the control. If you click the arrow for the slider, the value changes by min_step, while if you click the trough, the value changes by max_step. Each value must be in the range [0,1], and is a percentage of the range max-min. \item string - string - the text for the control. \item style - @|{'pushbutton','toggle','radiobutton','checkbox', 'edit','text','slider','frame','listbox','popupmenu'}|. \item tag - string - user specified label. \item tooltipstring - string the tooltip for the control. \item type - string - the text is set to 'uicontrol'. \item uicontextmenu - handle the handle of the uicontextmenu that shows up when you right-click over the control. \item units - not used. \item userdata - array - any data you want to associate with the control. \item value - The meaning of this property depends on the type of the control: - check box - set to max when checked, and min when off. - list box - set to a vector of indices corresponding to selected items, with 1 corresponding to the first item in the list. - pop up menu - set to the index of the item selected (starting with 1) - radio buttons - set to max when selected, and set to min when not selected. - sliders - set to the value of the slider - toggle buttons - set to max when selected, and set to min when not selected. - text controls, push buttons - do not use this property. \item visible - {'on','off'} - controls whether the control is visible or not \end{itemize}
