A CountDown shows a timer that counts down and which executes a callback upon reaching zero.
| BackgroundColor | RGB triple, default value is system dependent | The background color of the countdown component. |
| BusyAction | cancel | {queue} | Callback queuing. Determines how MATLAB handles the execution of interrupting callbacks. A running callback is the currently executing callback. The interrupting callback is the callback that tries to interrupt the running callback. The BusyAction property of the interrupting callback determines how MATLAB handles its execution. When the BusyAction property is set to: 'queue' ? Puts the interrupting callback in a queue to be processed after the running callback finishes execution. 'cancel' ? Discards the interrupting callback as MATLAB finishes execution. For information about how the Interruptible property of the callback controls whether other callbacks can interrupt the running callback, see the Interruptible property description. |
| Callback | String, cell array or function handle, default value: [] | Specifies the function that should be executed when the countdown has reached zero. |
| Children | The component's children. | |
| Clipping | clipping | Clipping mode. This property has no direct effect on the objects Use this property if you want to implement your own custom |
| ContextMenu | Handle, default value: [] | The handle of the context menu associated with the countdown object. The context menu is displayed whenever you right-click over the countdown component. Use the Matlab uicontextmenu function to create the context menu. |
| Enable | {on} | inactive | off | Disable or enable the component. This property controls how components respond to user interaction. Possible values for this property: on ? The component is operational (the default). inactive ? The component is not operational, but looks the same as when Enable is on. off ? The component is not operational and is grayed out. |
| Extent | Width and height are the dimensions of the rectangle. All measurements are in units specified by the Units property. | Position rectangle (read only). A four-element vector that defines the size and position of the component. It has the form: [xpos,ypos,width,height] The first two elements are always zero are the component's position on the x- and y-axis. w |
| FontAngle | {normal} | italic | Setting this property to italic selects a slanted version of the component's font, when it is available on your system. |
| FontName | String, default is system dependent. | The name of the font in which to display the text in the components. To display and print properly, this must be a font that your system supports. Use listfonts to list all available system fontnames. |
| FontSize | Integer, default value is system dependent. | A number specifying the size in pixels of the component's font. |
| FontUnits | {points} | normalized | inches | centimeters | pixels | This property determines the units used by the FontSize property. Normalized units interpret FontSize as a fraction of the height of the uicontrol. When you resize the uicontrol, MATLAB modifies the screen FontSize accordingly. pixels, inches, centimeters, and points are absolute units (1 point = 1/72 inch). |
| FontWeight | {normal} | bold | Setting this property to bold selects a bold version of the component's font, when it is available on your system. |
| ForegroundColor | RGB triple, default value is system dependent | The color of the text in the countdown component. |
| HorizontalAlignment | {leading} | trailing | left | right | center | The alignment of the countdown's contents along the X axis. |
| Interruptible | off | {on} | Callback routine interruption. Controls whether MATLAB can interrupt an object's callback function when subsequent callbacks attempt to interrupt it. |
| JavaHandle | Java object | The underlying java object. See javacomponent |
| MatlabHandle | Matlab handle | The handle of the associated Matlab container for this java object. See javacomponent |
| MaximumSize | Array, [width height] | The component's maximum size, measured in pixels. The preferred size indicates the best size for the component. The component should be no larger than its maximum size and no smaller than its minimum size. NOTE: Matlab may overrule this setting if the component is not in a Panel, ScrollPane, Toolbar, SplitPane or TabbedPane. |
| MinimumSize | Array, [width height] | The component's minimum size, measured in pixels. The preferred size indicates the best size for the component. The component should be no larger than its maximum size and no smaller than its minimum size. NOTE: Matlab may overrule this setting if the component is not in a Panel, ScrollPane, Toolbar, SplitPane or TabbedPane.rtain layout managers. |
| MouseClickedCallback | String, cell array or function handle, default value: [] | Specifies the function that should be executed when the mouse is clicked on the component |
| MouseEnteredCallback | String, cell array or function handle, default value: [] | Specifies the callback function that should be executed when the mouse enters the component. |
| MouseExitedCallback | String, cell array or function handle, default value: [] | Specifies the callback function that should be executed when the mouse exits the component. |
| NextFocusableComponent | Jacontrol, default value: [] | Specifies the next component to get the focus after this one. for example, when the tab key or shift-tab key is used. |
| Parent | The component's parent. | |
| Position | Array, [width height] | Size and location of the component. The rectangle defined by this property specifies the size and location of the component within the parent. Specify Position as [left bottom width height] left and bottom are the distance from the lower-left corner of the parent object to the lower-left corner of the component. width and height are the dimensions of the component. All measurements are in units specified by the Units property. |
| PreferredSize | Array, [width height] | The component's preferred size, measured in pixels. The preferred size indicates the best size for the component. The component should be no larger than its maximum size and no smaller than its minimum size. NOTE: Matlab may overrule this setting if the component is not in a Panel, ScrollPane, Toolbar, SplitPane or TabbedPane. |
| Seconds | Integer, default value: 0 | The time (number of seconds) displayed on the countdown object. If the component is counting down a callback is executed after this number of seconds has passed. Seconds is -1 if the countdown has been completed Note that this property can only be set when the countdown is stopped |
| String | String, default value: '' | The text displayed on the countdown object together with the remaining time. |
| Style | CountDown (Read only) | |
| Tag | String, default value: '' | User specified object identifier.
Use this tag i.c.w. gcjh('tag',parent) to find a modelit.ui.Jacontrol |
| TooltipString | String, default value: '' | The TooltipString property specifies the text of the tooltip associated with the countdown component. When the user moves the mouse pointer over the countdown component and leaves it there, the tooltip is displayed. HTML can be used to format the text. |
| Type | Read only property fixed to 'Jacontrol' | String with the object type. |
| Units | {pixels} | normalized | inches | centimeters | points | characters | Used to interpret the extent and position properties. All units are measured from the lower-left corner of the parent object. Normalized units map the lower-left corner of the parent object to (0,0) and the upper-right corner to (1.0,1.0). pixels, inches, centimeters, and points are absolute units (1 point = 1/72 inch). Character units are characters using the default system font; the width of one character is the width of the letter x, the height of one character is the distance between the baselines of two lines of text. If you change the value of Units, it is good practice to return it to its default value after completing your computation so as not to affect other functions that assume Units is set to the default value. |
| Userdata | Array, default value: [] | User specified data for this modelit.ui.Jacontrol object |
| VerticalAlignment | {center} | bottom | top | The alignment of the countdown's contents along the Y axis. |
| Visible | Off | {On} | Component visibility. By default, all jacontrols are visible. When set to off, the jacontrol is not visible, but still exists and you can query and set its properties. |
