AdjustSizeValue¶: Updates the width and height of this control according to its current style

AdjustType¶: Determines if and how the width and height of this control should be modified to take the fixed space dictated by the style of this control

ApplyStyleLookup()¶: Gets and applies the style of a TStyledControl.

AutoTranslate¶: Specifies whether the control’s text should be translated

BeginUpdate()¶

Marks the start of an update session of the control and its children. FMX.ListView.TAppearanceListView.BeginUpdate inherits from FMX.Controls.TControl.BeginUpdate. All content below this line refers to FMX.Controls.TControl.BeginUpdate. Marks the start of an update session of the control and its children. It increases the value of the FUpdating semaphore. A call to BeginUpdate must be complemented by calls to EndUpdate after the update is finished. FUpdating is an internal semaphore used to mark the process of control updating. Painting of a control is disabled while FUpdating is higher than 0.

DefaultStyleLookupName¶: Returns a string with the name of the default style of this control

EndUpdate()¶

Marks the end of an update session of the control and its children. FMX.ListView.TAppearanceListView.EndUpdate inherits from FMX.Controls.TControl.EndUpdate. All content below this line refers to FMX.Controls.TControl.EndUpdate. Marks the end of an update session of the control and its children.
