BreadcrumbNavigator QControl

The BreadcrumbNavigator QControl Code can be found here:

BreadcrumbNavigator QControl.zip

The QControl Toolkit is required to use this and can be found here:

The QControl Toolkit on LabVIEW Tools Network

Overview

For this QControl I had a need to mimic breadcrumb navigation similar to that found in a webpage. This QControl modifies a string control to display the elements. For those that don't know what breadcrumb navigation is, it is the history trail of where you have been (like Hansel and Gretel leaving a breadcrumb trail). It allows the user to return to any given point.

This QControl allows a developer to add items, change the delimiter (should be done at the start but default is the colon), and fires a user event when clicked so the user can handle the actual navigation.

To add an element, don't write to the strings value; instead use the AddString Property. The items will appear underlined just like a link on mouseover. On mouse click a user event is generated giving the selected string and the BreadcrumbNavigator QControl truncates the list to the clicked item.

See the included tester VI for implementation details.

RichTextBox QControl

The RichTextBox QControl Code can be found here: RichTextBox QControl.zip The QControl Toolkit is required to use this and can be found here : The QControl Toolkit on LabVIEW Tools Network Overview For this QControl I wanted a completely LabVIEW Rich Text Box. Under the hood it uses an HTML-like tagged string to define the formatting. Then there are two main methods: one that converts the tagged string to the formatted string and one that converts the formatted string to the tagged string. This QControl contains two classes. First, the RichTextBox Class inherits from the String Class and adds the ability read/write through a property nodes: the tagged string whether to view the tagged string value or the formatted value in the String Control Second, the RichTextBoxWithToolbar adds the Toolbar Facade and the Event Handler to handle all of the formatting events. The font l...

StatusHistory QControl

This is the second in a series of posts on some of the extended QControls that come already installed with the QControl Toolkit. There is no separate download for these. To get them just install the QControl Tool Kit available here: The QControl Toolkit on LabVIEW Tools Network After installed, examples can be found in the NI Example Finder and the Controls (Facades) and the methods can be found in the Addons-->QControl Palettes. Overview The StatusHistory QControl is a history stack which will display the last number of strings written to it. The history size, colors, and direction are settable properties. The StatusHistory QControl is what I used in the New QControl Wizard to get the cool vanishing text effect. There is an example in the Example Finder (shown below) when the toolkit is installed. Pictured here and in the New QControl Wizard I set the older strings in the stack to fade to the same color as my background to make the ...
