Status Bar

BuilderX comes with the Status Bar preview in order to view the precise design while building the app. You can enable/disable the preview of Status Bar in the Design Panel in the BuilderX workspace.

You can do so by clicking on the checkbox next to Show Status Bar to view the Status Bar on the Artboard.

Android Status Bar

When Device OS type is Android, The Device Tool will be rendered as shown below:

Android StatusBar

You can give a background color to the Status Bar when the device type is Android by clicking on the color picker next to Background Color shown in above image and set the desired color.

iOS Status Bar

For IOS, the background is translucent by default,so that it adjusts to your application design background. BuilderX takes that default setting as the status bar on your artboard.

iOS StatusBar
Bar Style

You can specify the type of the content in the bar. For example, for darker backgrounds, you can choose light-content and for lighter backgrounds, dark-content respectively.


Adding Rectangle

The easiest way to add a rectangle is to pick the rectangle shape from the Toolbar. Choose Insert > Shape and select Rectangle(or press R). You will see the pointer change to the Draw Rectangle tool icon +.

Left Toolbar Insert Popup

Now click on the Artboard and drag to insert your shape. When you release the pointer, the shape will be inserted and you can start manipulating it in other ways.

You can also click on the Artboard when your pointer tool is set to + and a pop-up will appear asking you to enter the desired dimensions of your rectangle.

Enter Dimension Popup

Providing the Width and Height will automatically be applied as the dimension of the inserted layer.


Adding Text

You can add text by choosing the Text tool from the Insert pop-up menu in the toolbar (or press T). The pointer changes to the Text Input tool icon and then you can click anywhere on the Artboard to insert your text layer at that point. A new text layer will be inserted with Text Added already selected, ready to replace.

Insert Text

You can also click-and-drag to create a text box of a fixed size. When the text gets too big to fit inside the box, it will create a new line, as opposed to a normal text box which increases its width to fit the content.

Resizing Text

When you resize a text box in the Canvas, its text size will not change. To change the text size, you must edit the text size value in the Design Panel.

In BuilderX, you can align text horizontally, vertically or centrally. In addition to this, you can also adjust the text alignment and determine whether the text should be at a fixed or automatic width/height.

Editing Text

When you have a text layer selected, you will notice that the Editor in the Design Panel changes to display all the properties that apply to a Text layer.

Under those, you can choose and apply the various text properties that you would expect, such as typeface (font-family), weight (e.g. light, bold, italic) and the font size. Additionally, you can also adjust text alignment, determine whether the layer should be at a fixed, or automatic width and adjust character, line, and paragraph spacings.

Text Color

When you’re editing text, you can apply specific colors to the text by using the Color button.

Text Alignment

In BuilderX, you can align text horizontally as well as vertically. In order to see the changes to a text layer’s alignment, you can set the text box to either Auto or Fixed.

Text Props Editor

When the alignment is set to Auto, the text box’s width will expand as wide as possible to fit the text you entered, and the horizontal alignment is taken into account when you type.

When the alignment is set to Fixed, you can click and drag the handles that appear on the Artboard to adjust the height and width of your text layer. When entering text, it’ll wrap around the box and a new line will be created when the text can’t fit in the width.

As well as being able to adjust the horizontal alignment, text can be aligned vertically to the top, middle, or bottom when you have given the text layer a Fixed height.


BuilderX uses Google Fonts to render text. You can also use local fonts using BuilderX Desktop Manager.

Text to TextInput

The Editable checkbox, when checked, converts simple text in code to a TextInput field, which is explained below.

Text Input

TextInput is a component that uses the keyboard to input text into an app. It provides configurability and lots of different features that make it versatile. You can find all its features here.


When an icon is selected, the Design Panel shows familiar options with some new ones. The Change Icon button allows you to replace the icon selected without changing its position on the artboard. The Styling option allows you to change the color, size as well as manage overflow for the icon.


Images are also supported in BuilderX as a layer. Images can be of many forms, such as screenshots or photographs, and cannot be edited or manipulated.

You can add an Image by choosing the Image tool from the Insert pop-up menu in the Toolbar (or press P). The pointer changes to the Image tool icon. You can then click anywhere on the Artboard, followed by a dialogue box to choose the image you wish to insert, upon selection of which a new Image layer will be inserted.

Insert Image

To replace an image in BuilderX with ease, simply select Change Image in the Image Editor in the Design Panel.

Resizing Image

Determines how to resize the image when the frame doesn't match the raw image dimensions.

To start editing an image, select Resize Mode under Image toolbar. You can also manipulate images freely.

The Resize Mode allows you to resize image with options like cover, contain, stretch, repeat and center.

  • Cover: This will scale the image uniformly (while maintaining the image's aspect ratio) so that both dimensions (width and height) of the image will be equal to or larger than the corresponding dimension of the layer.

  • Contain: This will scale the image uniformly (while maintaining the image's aspect ratio) so that both dimensions (width and height) of the image will be equal to or less than the corresponding dimension of the layer.

  • Stretch: This will scale width and height independently, This may change the aspect ratio of the source Image.

  • Repeat: This will repeat the image to cover the frame of the view. The image will keep it's size and aspect ratio.

  • Center: This will center the image in the view along both dimensions. If the image is larger than the view, scale it down uniformly so that it is contained in the view.

Change Image View

To start editing an image, select properties from Design Panel which allow you to edit width, height and alignment of the imasge. You can also apply border width , border radius , overflow and opacity properties to your images.


Adding Ellipse

The easiest way to add an Ellipse is to pick the Ellipse shape from the Toolbar. Choose Insert > Shape and select Ellipse(or press E). You will see the pointer change to the Draw Ellipse tool icon : heavy_plus_sign:.

Insert Ellipse

Now click on any point on the Artboard and drag to insert your shape. Upon releasing the pointer, the shape will be inserted and you can start manipulating it in other ways.

  • Snap to Grid
  • Snap to Layers
  • Snap to Document
  • Snap to Gutter
  • Snap to Ruler
