ActivityIndicator#

Qualified name: delphivcl.ActivityIndicator

class ActivityIndicator#

Bases: CustomActivityIndicator

An animated rotating display indicating that the application is performing some activity. Create the activity indicator, set the color, size and type, and set the Animate property to True to start the animation. You can modify the speed of the animation with the FrameDelay property.

Anchors#

Specifies how the control is anchored to its parent. Use Anchors to ensure that a control maintains its current position relative to an edge of its parent, even if the parent is resized. When its parent is resized, the control holds its position relative to the edges to which it is anchored. If a control is anchored to opposite edges of its parent, the control stretches when its parent is resized. For example, if a control has its Anchors property set to [akLeft, akRight], the control stretches when the width of its parent changes. Anchors is enforced only when the parent is resized. Thus, for example, if a control is anchored to opposite edges of a form at design time and the form is created in a maximized state, the control is not stretched because the form is not resized after the control is created.

Note: If a control should maintain contact with three edges of its parent (hugging one side of the parent and stretching the length of that side), use the Align property instead. Unlike Anchors, Align allows controls to adjust to changes in the size of other aligned sibling controls as well as changes to the parent’s size.

Animate#: Specifies whether the activity indicator is currently animated. Default is False.

BringToFront()#: Puts the control in front of all other controls in its parent control.

ClientToScreen()#: Translates a given point from client area coordinates to global screen coordinates.

FrameDelay#: Specifies how fast the activity indicator displays its animation sequence. Set this property to a lower value to speed up the animation.

Hide()#: Hides the wrapped Control

IndicatorColor#

The color of the activity indicator. Possible values are:

aicBlack: Default. The elements of the indicator are black. aicWhite: The elements of the indicator are white.

IndicatorSize#

The size of the activity indicator. Possible values are:

aisSmall: 24 x 24 pixels. aisMedium: Default. 32 x 32 pixels. aisLarge: 48 x 48 pixels. aisXLarge: 64 x 64 pixels.

IndicatorType#

The type of the activity indicator. Possible values are:

aitMomentumDots : Default. Traditional Windows 8/10 rotating sequence of dots, accelerating and deccelerating in a circular pattern. aitRotatingSector : Alternating sectors of a segmented ring are highlighted in sequence to indicate activity. aitSectorRing : Sectors of a segmented ring are highlighted in sequence until the ring is completely highlighted. On the next pass, each sector is displayed in a dimmed state.

Invalidate()#: Completely repaint control.

Parent#: Returns/Sets the Control Parent

Repaint()#: Forces the control to repaint its image on the screen.
