Control width in device-independent points.

Range: 0 to 100000.

Designer starting value: 160.

Height

Control height in device-independent points.

Range: 0 to 100000.

MinWidth

Minimum control width in device-independent points; 0 lets the parent layout choose.

Range: 0 to 100000.

MinHeight

Minimum control height in device-independent points; 0 lets the parent layout choose.

Range: 0 to 100000.

TabIndex

Keyboard navigation order within the parent container; lower values come first.

Range: 0 to 100000.

ZIndex

Stacking order among sibling controls; larger values appear in front. Equal values preserve document order.

Range: -100000 to 100000.

Anchor

Edges kept at their authored distance when the parent resizes. Use a comma-separated combination of Left, Top, Right and Bottom; Dock overrides the effective anchor without deleting it.

Dock

Automatic placement within the parent: None, Left, Top, Right, Bottom or Fill. Dock overrides effective Anchor layout without deleting the stored anchors.

Visible

Whether the control is shown in the running application.

Enabled

Whether the control accepts user interaction in the running application.

HitTestVisible

Whether the running control participates in pointer hit testing. The control remains selectable in the Designer.

AllowDrop

Whether this running control accepts application drag-and-drop operations; Designer movement is separate.

DragMode

VB control drag: 0 Manual (code starts a drag with the Drag method) or 1 Automatic (a left-button press starts a drag, and the control raises no Click, MouseDown or MouseUp for that press).

Range: 0 to 1.

DragIcon

Case-insensitive name of a declared project image resource shown under the pointer while this control is dragged; empty shows a grey outline of the control.

TabStop

Whether Tab navigation can move focus to this OptionButton.

Font

Font as Family|Size or Family|Size|Regular/Bold|Normal/Italic, size 6–96 DIP. Empty uses the theme font; System uses the theme family.

ForeColor

Text color as #RRGGBB. Empty uses the current macOS theme color.

BackColor

Background color as #RRGGBB. Empty uses the current macOS theme color.

Margin

External spacing as one non-negative DIP value or Left,Top,Right,Bottom.

Cursor

Pointer shown over the control: Default, Arrow, Hand, IBeam, Cross, Wait, Help, SizeAll, SizeNS, SizeWE, SizeNWSE, SizeNESW or NotAllowed.

Opacity

Visual opacity from 0 (transparent) to 1 (opaque).

Range: 0 to 1.

DesignLocked

Prevents movement and resizing in the Designer without changing runtime interaction.

AccessibleDescription

Additional help text announced by assistive technology.

AutomationId

Stable automation identifier; empty uses the component Name.

AccessibleName

Name announced by assistive technology. Empty uses the stable control Name.

AccessibleRole

Accessibility role override. Auto preserves the native semantic role; explicit values use the corresponding platform automation role.

ToolTipText

Help text shown when the pointer rests over the running control; empty disables the tooltip.

Tag

Application-defined text associated with this control; McBasic™ does not interpret it.

Caption

Text displayed by the control.

Designer starting value: "OptionButton".

WordWrap

Wraps the displayed caption within the available control width; false keeps a single line.

TextTrimming

Overflow behavior for an unwrapped caption: None, CharacterEllipsis or WordEllipsis.

Padding

Inner spacing around the glyph and caption as one non-negative DIP value or Left,Top,Right,Bottom.

Checked

Legacy BASIC/layout alias for Value. New designs edit Value; both names address one Boolean state.

Value

Canonical VB-compatible Boolean state of the OptionButton.

GroupName

Optional Form-wide exclusive group name. Empty groups the OptionButton with siblings in its immediate container.

Index

Position of this control in its control array, 0 to 32767. Several controls share one name only when every one of them has an Index. Absent from the layout, and -1 in code, when the control is not in an array.

Designer values: 0 to 32767. Clear the dedicated Index row for a non-array control; BASIC then reads -1.

Click

Occurs once when the component is logically activated by the user.

Private Sub control_Click()

No parameters.

Change

Occurs after the component value changes according to its McBasic™ change policy.

Private Sub control_Change()

No parameters.

DragEnter

Occurs when runtime drag data enters this control; set Effect to Copy, Move, Link or None.

Private Sub control_DragEnter(ByVal Data As DragData, ByRef Effect As DragEffect, ByVal X As Double, ByVal Y As Double)

DragOver

Occurs while runtime drag data moves over this control; Effect may be updated for the current position.

Private Sub control_DragOver(ByVal Data As DragData, ByRef Effect As DragEffect, ByVal X As Double, ByVal Y As Double)

DragOver

Occurs while a control dragged inside the app (DragMode or the Drag method) moves over this control: State is 0 when it enters, 2 while it moves over and 1 when it leaves; Source is the dragged control and X, Y are local DIP coordinates.

Private Sub control_DragOver(ByVal Source As Control, ByVal X As Single, ByVal Y As Single, ByVal State As Integer)

DragLeave

Occurs when runtime drag data leaves this control without a drop.

Private Sub control_DragLeave()

No parameters.

Drop

Occurs when runtime drag data is dropped on this control with a stable McBasic™ effect and local DIP coordinates.

Private Sub control_Drop(ByVal Data As DragData, ByVal Effect As DragEffect, ByVal X As Double, ByVal Y As Double)

DragDrop

Occurs when a control dragged inside the app (DragMode or the Drag method) is released over this control; Source is the dragged control and X, Y are local DIP coordinates.

Private Sub control_DragDrop(ByVal Source As Control, ByVal X As Single, ByVal Y As Single)

MouseDown

Occurs when a pointing-device button is pressed over this control; Button is stable McBasic™ identity and X/Y are control-local DIP coordinates.

Private Sub control_MouseDown(ByVal Button As MouseButton, ByVal Shift As KeyModifiers, ByVal X As Double, ByVal Y As Double)

MouseUp

Occurs when a pointing-device button is released for this control; Button is stable McBasic™ identity and X/Y are control-local DIP coordinates.

Private Sub control_MouseUp(ByVal Button As MouseButton, ByVal Shift As KeyModifiers, ByVal X As Double, ByVal Y As Double)

MouseMove

Occurs when the pointer moves over the logical McBasic™ control; Button contains the currently held buttons and X/Y are local DIP coordinates.

Private Sub control_MouseMove(ByVal Button As MouseButtons, ByVal Shift As KeyModifiers, ByVal X As Double, ByVal Y As Double)

MouseEnter

Occurs once when the pointer enters the effective bounds of the logical McBasic™ control.

Private Sub control_MouseEnter()

No parameters.

MouseLeave

Occurs once when the pointer leaves the effective bounds of the logical McBasic™ control.

Private Sub control_MouseLeave()

No parameters.
