Button customization

…ccur within the specified number (e.g., fast double-clicks) will be considered by the component as only a single click. The default value of 0 means that all clicks will be processed separately, which is often undesirable in GUI applications. Remember that the value is in milliseconds, not seconds. FlyOverAppearance – boolean flag (default=false); if set, the button appearance is changed to a flat (2D) appearance with a special 3D border… Continue reading

Waterloo graphics

…for example to create graphical insets. Multi-layered graphs, with each layer having independent axes. Figure 2: A multi-layered graph. Each plot has its own graph layer with independent axes. Built-in mouse interactivity and GUIs for interactive plot editing. Figure 3: A plot editor for a single-layered graph. Java programmers might note here the use of a few custom-designed Swing widgets: a dial that subclasses JSlider and supports multiple-tur… Continue reading

Transparent labels

…available space for a new label. I could drive the entire content down to make space for it, but that would reduce the usable space for the actual contents, which is already at a premium: Adding a transparent label to Matlab GUI (click for full-size image) A natural place for the new label, as indicated, would be on top of the empty space next to the content’s sub-tabs (Correlation and Backtesting). This empty space is taken up by Matlab&#… Continue reading

Matlab layout managers: uicontainer and relatives

When designing Matlab applications, we can either use Matlab’s designer (guide), or manually position each GUI component programmatically, using its Position property. Matlab lacks the layout managers so common in Java, that enable easy relative component positioning, taking into account dynamic container size, components spacing weights etc. Of course, we can always trap the container’s ResizeFcn callback to update our layout, but d… Continue reading

Animated busy (spinning) icon

Matlab includes a wide variety of internal widgets (GUI components) that could be very useful in our GUIs. One such widget is an animated spinning icon, which is often used by Matlab itself and numerous toolboxes to illustrate a running task: Sample usage of an animated spinning icon One of the internal widgets that are readily-available for use in our Matlab GUI and displays a similar (but not identical) spinning icon is BusyAffordance, which i… Continue reading

Customizing uitree

Last week, I introduced the semi-documented uitree function that enables displaying data in a hierarchical (tree) control in Matlab GUI. Today, I will continue by describing how uitrees can be customized. Note that although uitrees use Java objects internally, we can create and customize uitree using pure-Matlab code. Creating non-standard tree types To start the discussion, let’s create a simple uitree whose Root node is not one of the a… Continue reading

Color selection components

A couple of weeks ago, a reader of this website requested an article about color-selection components. So Ed – this one’s for you Matlab includes a fully-documented uisetcolor function to enable color selection. uisetcolor uses a modal dialog window for this. To integrate this color-selection dialog in our GUI, simply add a uicontrol button or a menu item that call uisetcolor in their callback function. An example of such an integra… Continue reading

Uicontrol callbacks

…either directly or because its container was resized. ComponentShownCallback – fired when the component is displayed (setVisible(true)). Compare: ComponentHiddenCallback FocusGainedCallback – fired when the component gains GUI focus, by mouse click, Tab click, or calling the component’s requestFocus() method. FocusLostCallback – fired when the component loses focus to another component or window. Compare: FocusGainedCallback Hierarchy… Continue reading

Customizing uitree nodes – part 2

In my previous posts I have shown how Matlab’s semi-documented uitree and uitreenode functions can be used to display hierarchical (tree) control in Matlab GUI. Today I conclude this mini-series by answering a reader’s request to show how checkboxes, radio buttons and other similar controls can be attached to tree nodes. There are actually several ways this can be done: Matlab icon control The simplest is to create two icons (checked… Continue reading

Date selection components

Have you ever wondered why Matlab does not have standard GUI date-handling components? Matlab has many built-in date-handling functions (calendar, date, datestr, datenum, datetick, datevec etc.). Unfortunately, this built-in support does not extend to Matlab GUI. If we need a date-selection drop-down or calendar panel we have to design it ourselves, or use a third-party Java component or ActiveX control. JIDE Components Luckily, we have a much… Continue reading
