Range: 0 to 100000.

Height

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.

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.

Margin

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

Visible

Whether the container is shown in the running application.

BackColor

Container background color as #RRGGBB. Empty uses the current theme background.

BorderStyle

Container border style: Solid draws the configured border; None removes it without discarding the authored color or width.

BorderColor

Container border color as #RRGGBB. Empty uses the current theme border color.

BorderWidth

Container border width in device-independent points.

Range: 0 to 100.

CornerRadius

Container corner radius in device-independent points.

Range: 0 to 1000.

Padding

Inner spacing as one non-negative DIP value or Left,Top,Right,Bottom; child coordinates remain relative to the padded content area.

ClipToBounds

Whether authored child content is clipped to the scroll viewport bounds.

AccessibleName

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

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.

AccessibleRole

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

AutomationId

Stable automation identifier; empty uses the component Name.

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.

Enabled

Whether children in the container accept user interaction.

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.

HorizontalScrollBar

Horizontal scrolling policy: Auto, Visible, Hidden or Disabled. When authored, this per-axis value takes precedence over the legacy ScrollBars alias.

VerticalScrollBar

Vertical scrolling policy: Auto, Visible, Hidden or Disabled. When authored, this per-axis value takes precedence over the legacy ScrollBars alias.

HorizontalOffset

Current horizontal scroll position in device-independent points. This runtime value is read-only and is not stored in the Form layout.

Range: 0 to 100000.

VerticalOffset

Current vertical scroll position in device-independent points. This runtime value is read-only and is not stored in the Form layout.

Range: 0 to 100000.

ScrollBars

Legacy compatibility alias: Both, Horizontal, Vertical or None map each enabled axis to Auto and each disabled axis to Disabled. Use the per-axis properties for new forms.

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.

Scroll

Occurs after the horizontal or vertical scroll offset changes.

Private Sub control_Scroll()

No parameters.

Resize

Occurs after the effective control size changes.

Private Sub control_Resize()

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.

MouseWheel

Private Sub control_MouseWheel(ByVal Delta As Double, ByVal Shift As KeyModifiers, ByVal X As Double, ByVal Y As Double)

DoubleClick

Occurs when native system timing recognizes a primary-button double activation on the same logical McBasic™ control.

Private Sub control_DoubleClick()

No parameters.
