Some Controls in depth

Controls make the visual elements of your app.

An app will have one or more forms. Each form will have a collection of controls on it, customized by you with different sizes and appearances.

In this section, we will see how to add controls and forms to an app.

Add controls to your app by dragging and dropping them into place. Then, resize and set the properties.

Let's look at some controls.

Label

Controls are defined by their properties. The Label control is a simple control. Most of the properties for a control are set to default values when the control is created, so it is usable right away. Let's look at the options for customizing it.

align	left, center, right
alignVertical	top, center, bottom (no % or multiline)
backgroundColor	colors can be a name, #RRGGBB, rgb(R,G,B) or transparent
borderColor
borderStyle	solid, dotted, dashed, etc.
borderWidth	pixels
bottom	pixels, percent, auto
class	grayTitle default. Can be custom css.
color	Of the text
fontFamily	helvetica is default
fontSize	in pixels. 16 is the default.
fontStyle	normal, italic or oblique
fontWeight	normal, bold or a number
height
hidden	true or false
id	The name of the control.
left
onclick, etc	names of functions to be called when these events happen.
right
style	css style
textContent	The content of the label. HTML is OK!
top
width

TextBox

The TextBox has many of the same properties as the label - plus some additional ones:

autocapitalize	Automatically capitalize first letter? May not be available on all platforms.
autocomplete	Automatically complete words? May not be available on all platforms.
autocorrect	Spellcheck as entering? May not be available on all platforms.
inputType	Specifies what kind of data will be input. Choices are: color date datetime email file (iOS 6+ and Android 4+ only) hidden month number password range search tel text (default) time url
placeholder	Text to be displayed in the field just as a comment – does not change the value.
readonly	If set to “True”, the control cannot be edited. At runtime, use readOnly.
size	Maximum characters allowed.
text	The contents of the TextBox. Same as value.
value	The contents of the TextBox. This is always returned as a string. Convert it to a number before doing arithmetic on it – see “Conversions”.

Button
