Detailed Description

This class is used to display a Slider.

Example Slider icon

A Slider is a progress bar that adds a draggable thumb. You can touch the thumb and drag left or right to set the slider thumb position. As the Slider thumb is dragged, it will trigger the PositionChanged(float) event, reporting the position of the Slider thumb. The reported position of the thumb can be used to dynamically update another component attribute, such as the TextBox#FontSize(float) of a TextBox or the Radius of a Ball.

The Slider uses the following default values. However these values can be changed through the Designer or Blocks editor:

Member Function Documentation

◆ ColorLeft() [1/2]

int com.google.appinventor.components.runtime.Slider.ColorLeft ( )

Returns the color of the slider bar to the left of the thumb, as an alpha-red-green-blue integer, i.e.,

0xAARRGGBB

. An alpha of

00

indicates fully transparent and

FF

means opaque.

Returns: left color in the format 0xAARRGGBB, which includes alpha, red, green, and blue components

Definition at line 355 of file Slider.java.

◆ ColorLeft() [2/2]

void com.google.appinventor.components.runtime.Slider.ColorLeft ( int argb )

Specifies the color of the slider bar to the left of the thumb as an alpha-red-green-blue integer, i.e.,

0xAARRGGBB

. An alpha of

00

indicates fully transparent and

FF

means opaque.

Parameters

argb	background color in the format 0xAARRGGBB, which includes alpha, red, green, and blue components

Definition at line 370 of file Slider.java.

◆ ColorRight() [1/2]

int com.google.appinventor.components.runtime.Slider.ColorRight ( )

Returns the color of the slider bar to the right of the thumb, as an alpha-red-green-blue integer, i.e.,

0xAARRGGBB

. An alpha of

00

indicates fully transparent and

FF

means opaque.

Returns: right color in the format 0xAARRGGBB, which includes alpha, red, green, and blue components

Definition at line 387 of file Slider.java.

◆ ColorRight() [2/2]

void com.google.appinventor.components.runtime.Slider.ColorRight ( int argb )

Specifies the color of the slider bar to the right of the thumb as an alpha-red-green-blue integer, i.e.,

0xAARRGGBB

. An alpha of

00

indicates fully transparent and

FF

means opaque.

Parameters

argb	background color in the format 0xAARRGGBB, which includes alpha, red, green, and blue components

Definition at line 402 of file Slider.java.

◆ getView()

View com.google.appinventor.components.runtime.Slider.getView ( )

Returns the View that is displayed in the UI.

Reimplemented from com.google.appinventor.components.runtime.AndroidViewComponent.

Definition at line 408 of file Slider.java.

◆ Height() [1/2]

int com.google.appinventor.components.runtime.Slider.Height ( )

Returns the component's vertical height, measured in pixels.

Returns: height in pixels

Reimplemented from com.google.appinventor.components.runtime.AndroidViewComponent.

Definition at line 454 of file Slider.java.

◆ Height() [2/2]

void com.google.appinventor.components.runtime.Slider.Height ( int height )

Specifies the component's vertical height, measured in pixels.

Parameters

height in pixels

Reimplemented from com.google.appinventor.components.runtime.AndroidViewComponent.

Definition at line 466 of file Slider.java.

◆ MaxValue() [1/2]

float com.google.appinventor.components.runtime.Slider.MaxValue ( )

Returns the slider max value

@suppressdoc

Returns: the slider max value

Definition at line 338 of file Slider.java.

◆ MaxValue() [2/2]

void com.google.appinventor.components.runtime.Slider.MaxValue ( float value )

Sets the maximum value of slider. If the new maximum is less than the current minimum, then minimum and maximum will both be set to this value. Setting MaxValue resets the thumb position to halfway between MinValue() and MaxValue and signals the PositionChanged(float)` event.

Definition at line 320 of file Slider.java.

◆ MinValue() [1/2]

float com.google.appinventor.components.runtime.Slider.MinValue ( )

Returns the value of slider min value.

@suppressdoc

Returns: the value of slider min value.

Definition at line 302 of file Slider.java.

◆ MinValue() [2/2]

void com.google.appinventor.components.runtime.Slider.MinValue ( float value )

Sets the minimum value of slider. If the new minimum is greater than the current maximum, then minimum and maximum will both be set to this value. Setting MinValue resets the thumb position to halfway between MinValue and MaxValue() and signals the PositionChanged(float)` event.

Definition at line 282 of file Slider.java.

◆ onProgressChanged()

void com.google.appinventor.components.runtime.Slider.onProgressChanged	(	SeekBar	seekBar,
		int	progress,
		boolean	fromUser
	)

Definition at line 413 of file Slider.java.

◆ onStartTrackingTouch()

void com.google.appinventor.components.runtime.Slider.onStartTrackingTouch ( SeekBar seekBar )

Definition at line 439 of file Slider.java.

◆ onStopTrackingTouch()

void com.google.appinventor.components.runtime.Slider.onStopTrackingTouch ( SeekBar seekBar )

Definition at line 444 of file Slider.java.

◆ PositionChanged()

void com.google.appinventor.components.runtime.Slider.PositionChanged ( float thumbPosition )

Indicates that position of the slider thumb has changed.

Definition at line 434 of file Slider.java.

◆ ThumbEnabled() [1/2]

boolean com.google.appinventor.components.runtime.Slider.ThumbEnabled ( )

Whether or not the slider thumb is being be shown.

Returns: Whether or not the slider thumb is being be shown

Definition at line 226 of file Slider.java.

◆ ThumbEnabled() [2/2]

void com.google.appinventor.components.runtime.Slider.ThumbEnabled ( boolean enabled )

Sets whether or not the slider thumb should be shown
