Show Slide: What is a GUI Builder Toolbox?	What is a GUI Builder Toolbox? GUI Builder Toolbox in Scilab: Is one of the ways to create a GUI. GUI is the abbreviation for Graphical User Interface.
Show Slide: Advantages of using GUI Builder Toolbox	Now let us look at the advantages of the Toolbox. The toolbox auto-generates a Scilab code for a GUI with object handle properties. This allows the user to build the GUI with ease. In the absence of this toolbox, users must write code from scratch to build the GUI.
	Let’s first learn to install the GUI Builder toolbox. This can be done in a number of ways. We will look at one of them.
Cursor on Scilab console. Type atomsGui and press Enter.	Open Scilab. In the Scilab console window, type atomsGui. The commands are case sensitive. Hence, please retain the syntax as shown here. Press Enter.
Cursor on Main categories - ATOMS window.	The Main categories - ATOMS window opens. This window has two panels. The left panel displays a list of toolbox categories.
Cursor on the blank right panel.	Notice that the right panel is blank since I have not installed the toolbox. It will display the details of the toolbox after installation.

Cursor on the GUI Builder Palette window, click on the Pushbutton.	Let us create a GUI by placing objects in this window. Go to the GUI Builder palette and click on the Pushbutton.
Cursor on Scilab Multiple Values Request window. Hover cursor over Tag.	A window named Scilab Multiple Values Request opens. Notice the Tag field. It is a unique identifier for each GUI object. It allows you to give a name to the object. A Tag can be a number or an alphabet or its combination. Users can assign any value as a Tag.
Type h1 in the Tag field.	I will type h1 in the Tag field.
Cursor on Scilab Multiple Values Request window, hover cursor over String.	Below Tag, we see the String field.
Cursor on Scilab Multiple Values Request window, Type Print in the String field. Click on OK.	The text in the String field is the display name for the object in the Graphic window. I will type Print in the String field and then, click on OK.
