# uipanel

Creates a frame for interactive graphical control objects in a figure.

## Syntax

h = uipanel()

h = uipanel(property, value, ...)

h = uipanel(parent, property, value, ...)

## Inputs

parent
Handle of a container object, which could be a figure, frame, uipanel, or uibuttongroup.
Type: double | integer
Dimension: scalar
property, value
'aspectratio'
Specifies if the aspect ratio for 'backgroundimage' needs to be ignored ('off') or kept ('on'). Default value is 'off', and the 'backgroundimage' is resized to the dimensions of h.
Type: string
'backgroundcolor'
Specifies the background color. Valid values are 'transparent' or a real vector specifying RGB values in the range 0-255 or 0-1.
Type: string | vector
'backgroundimage'
Specifies the background image; requires a path to a valid image file.
Type: string
'bordertype'
Specifies the border type. Valid options are 'beveledin' | 'beveledout' | 'etchedin' (default) | 'etchedout' | 'line' | 'none'
Type: string
'borderwidth'
Specifies the width of the border. Default value is 1.
Type: integer
'createfcn'
Function that is triggered when h is created. If value is a function handle, it must be a function that takes at least two arguments. The first argument is the handle of the uicontrol. The second argument is the event data to the uicontrol, which is ignored for createfcn. If value is a string, it must represent a function handle or a function name. If value is a cell, it must contain the function name/function handle in the first cell element and parameters to pass to callback function in the additional elements. After it is executed, createfcn cannot be interrupted.
Type: cell | functionhandle | string
'deletefcn'
Function that is triggered when h is deleted. If value is a function handle, it must be a function that takes at least two arguments. The first argument is the handle of the uicontrol. The second argument is the event data to the uicontrol, which is ignored for createfcn. If value is a string, it must represent a function handle or a function name. If value is a cell, it must contain the function name/function handle in the first cell element and parameters to pass to callback function in the additional elements. After it is executed, createfcn cannot be interrupted.
Type: cell | functionhandle | string
'fontangle'
Specifies the angle of the displayed font. Valid values are 'regular'(default) and 'italic'.
Type: string
'fontname'
Specifies the name of the displayed font.
Type: string
'fontsize'
Specifies the size of the displayed font.
Type: scalar
'fontweight'
Specifies the weight of the displayed font. Valid values are 'normal'(default) and 'bold'.
Type: string
'parent'
Specifies the parent.
Type: scalar
'position'
Position and size of h. Value is specified as a vector of form: [left top width height]. If 'units' has a value of 'normalized', values must be between 0 to 1.
Type: vector
'string'
Text to be displayed on h.
Type: string
'tag'
User-defined string to tag graphical control objects.
Type: string
'units'
Specifies units of measurement. Valid values are 'pixels'(default) and 'normalized'. Value 'pixel' indicates that h has a fixed size and position specified by 'position'. Value 'normalized' indicates that h will be resized if parent is resized.
Type: string
'userdata'
User-defined numerical data.
Type: complex | mtx | scalar
'visible'
Specifies if h is visible. Valid values are 'on'(default) and 'off'.
Type: string

## Outputs

h
Handle of the uipanel.

## Example

Creates a uipanel with a background image:
f = gcf;
panel = uipanel(f, 'units', 'normalized', 'position', [0, 0, 0.99, 0.3], 'backgroundimage', 'image1.jpg');
