uicontrol
create a Graphic User Interface object
Syntax
h = uicontrol(PropertyName,PropertyValue,...) h = uicontrol(parent,PropertyName,PropertyValue,...) h = uicontrol(uich)
Description
This routine creates an object in a figure.
If the handle of the figure is given (as the first parameter), the
uicontrol is created in this figure. If no handle is given, the uicontrol
is created in the current figure (which may be obtained with a call to
gcf()
). If there is no current figure, then one is
created before the creation of the uicontrol.
Then when the control is created, the properties given as parameters
are set with the corresponding values. It is equivalent to create the
uicontrol, and then set its properties with the set()
command. Nevertheless, it generally more efficient to set the properties
in the call to uicontrol()
. Scilab
and all the graphic objects communicate through the property mechanism.
Thus, to create adapted uicontrol, one has to know the use of the property
fields.
h = uicontrol(PropertyName, PropertyValue,...)
creates an uicontrol and assigns the specified properties and values to
it. It assigns the default values to any properties you do not specify.
The default uicontrol style is a "Pushbutton". The default parent is the
current figure. See the Properties section for information about these and
other properties.
h = uicontrol(parent, PropertyName, PropertyValue,...)
creates a uicontrol in the object specified
by the handle, parent. If you also specify a different value for the
Parent property, the value of the Parent property takes precedence. parent
is the handle of a figure.
h = uicontrol(uich)
gives focus to the uicontrol
specified by uich.
All available properties and their description are given in the uicontrol properties help page.
Uicontrols rendering and properties display can be customized using Console properties.
Available styles
The available styles are listed below. The style
of an uicontrol
must be set at creation using the "Style"
property and can not be changed once the uicontrol
is created.
Checkbox: a button with two states (Used for multiple independent choices).
Edit: an editable string zone.
Frame: a container for other uicontrols or axes.
Image: a component where a specified image is displayed.
Layer: a container for
frame
style uicontrols enabling to switch between them programmatically using thevalue
property.Listbox: a control representing a list of items that can be scrolled. The items can be selected with the mouse.
Popupmenu: a button which make a menu appear when clicked.
Pushbutton: (default style) a rectangular button generally used to run a callback.
Radiobutton: a button with two states. RadioButtons are intended to be mutually exclusive.
Your code must implement mutually exclusive behavior if you do not use groups (See
GroupName
property in uicontrol properties).Slider: a scale control, that is a slider used to set values between in range with the mouse.
Spinner: a component which enables the user to select/edit a value between bounds with a fixed step.
Tab: a container for
frame
style uicontrols enabling to switch between them by clicking on a tab with a given title and/or icon.The font related properties set on the frame will be used for the tab label.
Table: an editable table.
Text: a text control (generally static).
Examples
f=figure(); // create a figure h=uicontrol(f,'style','listbox', ... 'position', [10 10 150 160]); // create a listbox set(h, 'string', "item 1|item 2|item3"); // fill the list set(h, 'value', [1 3]); // select item 1 and 3 in the list close(f); // close the figure
uicontrol function can be overloaded
// create a mlist mymlist = mlist(['objid','A','B'],[],[]); // overload set / get for objid function result=%objid_uicontrol(varargin) // res = uicontrol(mymlist,'A'); obj_tmp = varargin(1); field_tmp = varargin(2); mprintf('uicontrol on an object of type %s, field = %s\n', typeof(obj_tmp), field_tmp); result = %t; endfunction res = uicontrol(mymlist,'property');
Pushbuttons or Text can have LaTeX or MathML label
// LaTeX f=figure(); h=uicontrol(f,"style","pushbutton","string","$x^2$"); // MathML hh=uicontrol(f,"style","pushbutton","string","<msup><mi>x</mi><mn>2</mn></msup>"); hh.Position = h.Position + [50, 0, 0, 0]; // Text h=uicontrol(f,"Style","text","string","$\Gamma(s)=\int_0^\infty t^{s-1}\mathrm{e}^{-t}\,\mathrm{d}t$"); // If it is too little h.fontsize=20
// Include an editable table into a figure: // Building a table of data: params = [" " "Country" "Population [Mh]" "Temp.[°C]" ]; towns = ["Mexico" "Paris" "Tokyo" "Singapour"]'; country = ["Mexico" "France" "Japan" "Singapour"]'; pop = string([22.41 11.77 33.41 4.24]'); temp = string([26 19 22 17]'); table = [params; [ towns country pop temp ]] f = gcf(); clf as = f.axes_size; // [width height] ut = uicontrol("style","table",.. "string",table,.. "position",[5 as(2)-100 300 87],.. // => @top left corner of figure "tooltipstring","Data from majors towns") // Modify by hand some values in the table. Then get them back from the ui: matrix(ut.string,size(table))
