EZText | SuperCollider 3.13.0 Help

Description

EZText is a wrapper class which creates an (optional) StaticText, and a TextField. The value is displayed as a compileString in the text field for editing.

Some Important Issues Regarding EZText

If the parent is nil, then EZText will create its own Window. See EZGui for more options.

Class Methods

EZText.new(parent, bounds, label, action, initVal, initAction: false, labelWidth: 60, textWidth, labelHeight: 20, layout: 'horz', gap, margin)

Arguments:

parent	The parent view or window. If the parent is nil, then EZText will create its own Window, and place it conveniently on the screen if the bounds are a Point. If the bounds are a Rect, then the Rect determines the window bounds.
bounds	An instance of Rect or Point. Default value is `160@20`.
label	The label. Default value is `nil`. If `nil`, then no StaticText is created.
action	A Function called when the value changes. The function is passed the EZText instance as its argument.
initVal	The value to initialize the EZText with.
initAction	A Boolean indicating whether the action function should be called when setting the initial value. The default is false.
labelWidth	Number of pixels width for the label. The default is 60. In the `\horz` layout, if you specify the `textWidth`, then the `labelWidth` is ignored and is set to the `bounds.width - textWidth`.
textWidth	Number of pixels width for the number box. The default is 45. In `\vert` layout, `textWidth` defaults to the `bounds.width`.
labelHeight	Default is 20.
layout	`\vert`, or `\horz`. The default is `\horz`; `\vert` is a two line version.
gap	A Point. By default, the view tries to get its parent's gap, otherwise it defaults to `2@2`. Setting it overrides these.
margin	A Point. This will inset the bounds occupied by the subviews of view.

Discussion:

Example:( w = Window("EZText", Rect(300, 300, 260, 60)).front; g = EZText( w, // parent 250@50, // bounds "testing", // label { |ez| (ez.value.asString ++" is the value of " ++ ez).postln }, // action [1, 2, 3], // initValue true // initAction ); g.setColors(Color.grey,Color.white); ); // Simplest version, no parent view, so a window is created ( g = EZText(label:" test "); g.action_({ |ez| (ez.value.asString ++" is the value of " ++ ez).postln }); ); ( g = EZText(bounds: Rect( 100, 200, 150, 50), label:" test ", layout: \vert); g.action_({ |ez| (ez.value.asString ++" is the value of " ++ ez).postln }); );

The contained views can be accessed via the EZText instance variables: labelView, textField.

Inherited class methods

Instance Methods

.textField

Returns the textField.

.action

.action = value

From superclass: EZGui

A Function to be evaluated when the value changes. Typical use is to type in a new value, and interpret it by hitting the evaluation shortcut. The first argument to the function will be the EZText.

.value

.value = inval

From superclass: EZGui

Gets/sets the value of the ezText. Does not perform the action.

Arguments:

inval

Any object.

.valueAction = val

From superclass: EZGui

Sets the value and performs the action.

Arguments:

val	Any object.

.doAction

From superclass: EZGui

Performs the action.

.enabled

.enabled = bool

From superclass: EZGui

Sets/gets whether the textfield is enabled.

Arguments:

bool	An instance of Boolean. Default is `true`.

Changing Appearance

.setColors(stringBackground, stringColor, textBackground, textStringColor, textNormalColor, textTypingColor, background)

Arguments:

stringBackground	An instance of Color. The `background` of the label and unit views.
stringColor	An instance of Color. The `stringColor` of the label and unit views.
textBackground	An instance of Color. The `background` of the textField.
textStringColor	An instance of Color. The `stringColor` of the textField.
textNormalColor	An instance of Color. The `normalColor` of the textField.
textTypingColor	An instance of Color. The `typingColor` of the textField.
background	An instance of Color. The `background` of the enclosing view.

.font = font

Set the Font used by all the views.

Arguments:

font	An instance of Font.
