LargeScrollbars QControl

This is the last 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 LargeScrollbar QControl operates just like a regular scrollbar except that, when using the included facades, is it large format for touchscreen control.  Pictured is a Multicolumn Listbox using two instances: one for vertical and one for horizontal:



The Scrollbars work by the main application using the Value Change Event on the slider in the facade and using the value to set the position of the String, Listbox, or in the example case, a Multicolumn Listbox.


The gives that benefit that this code can be reused multiple ways, as vertical or horizontal, or with multiple different types of controls.

If it is desired to further encapsulate the function of the scrollbars with a specific control,  it is recommended to create a new child class.  Then in that class include the control in the cluster and put the code above into the Event Handler Method.

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 ...

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 lin...
