Steps QControl

This is the fourth 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 Steps QControl handles the pages in a Tab Control to aid in making step-by-step wizards.  It is used in the QControl Creation Wizard given as part of the QCtonrol Toolkit, shown below:


In the Steps QControl Class there are three public methods:
  1. Goto Start Method - Enables the first page, disables all the other pages, and sets the Tab Control to the first page.
  2. Next Method - Enables the next page, disables all the other pages, and sets the Tab Control to the next page.
  3. Back Method - Enables the previous page, disables all the other pages, and sets the Tab Control to the previous page.
These are used in the owning VI using the Steps QControl to navigate through the pages.  The Next and Back Methods are smart enough to know when the first and last pages have been reached and will do nothing if used to try to move past the existing pages.

Therefore, in the main VI of the QControl Creation Wizard, the Goto Start Method is used on the initialize.  Then when the Next button is clicked, the Next Method is executed which moves the QControl Creation Wizard to the next step.


The Back button is made visible and if it were pressed the QControl Creation Wizard would return to the first step. 

The Next and Back buttons are not part of the Steps QControl so changing their properties (visibility, text, etc.) and the value change events are handled in the QControl Creation Wizard's code.

    Dear Q,
    I've installed Qcontrol through VIPM on LabVIEW 2017 (french), but the "New ..." menu doesn't show me the Qcontrol wizard. Is ther an other path to access to the wizard ?

    Philippe, I have attempted to answer your question on the QControl thread in the UI Interest Group in the NI Community Pages located here:

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 list is populated based on the OS and there is a case structure for that in

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 disappearing effect.  Ho

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 us
