Left
Horizontal position in device-independent points, relative to the parent container.
Range: -100000 to 100000.
Present a caption or status without inviting the user to edit it.
The name belongs in txtName.Text; the result belongs in lblGreeting.Caption. A Click handler is the bridge between them. Trimming before testing length rejects whitespace-only input. The details window has its own public DisplayName field: set that value before calling Show so its Shown handler can render it.
Add Label to its intended parent and name it lblGreeting for this example:
| Property | Example value |
|---|---|
Caption | "Enter your name and click Greet." |
Use the full lesson for the owner’s initialization code and its complete layout.
Contract defaults are shown below. Where a new control has a different Designer starting value, that value is listed separately.
LeftHorizontal position in device-independent points, relative to the parent container.
Range: -100000 to 100000.
TopVertical position in device-independent points, relative to the parent container.
Range: -100000 to 100000.
WidthControl width in device-independent points.
Range: 0 to 100000.
Designer starting value: 180.
HeightControl height in device-independent points.
Range: 0 to 100000.
MinWidthMinimum control width in device-independent points; 0 lets the parent layout choose.
Range: 0 to 100000.
MinHeightMinimum control height in device-independent points; 0 lets the parent layout choose.
Range: 0 to 100000.
MaxWidthMaximum control width in device-independent points.
Range: 0 to 100000.
MaxHeightMaximum control height in device-independent points.
Range: 0 to 100000.
TabIndexKeyboard navigation order within the parent container; lower values come first.
Range: 0 to 100000.
ZIndexStacking order among sibling controls; larger values appear in front. Equal values preserve document order.
Range: -100000 to 100000.
AnchorEdges 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.
DockAutomatic placement within the parent: None, Left, Top, Right, Bottom or Fill. Dock overrides effective Anchor layout without deleting the stored anchors.
VisibleWhether the control is shown in the running application.
EnabledWhether the control accepts user interaction in the running application.
HitTestVisibleWhether the running control participates in pointer hit testing. The control remains selectable in the Designer.
AllowDropWhether this running control accepts application drag-and-drop operations; Designer movement is separate.
DragModeVB 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.
DragIconCase-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.
CaptionText displayed by the control.
Designer starting value: "Label".
WordWrapWraps the caption within the Label width; false keeps a single line.
TextTrimmingOverflow behavior for an unwrapped caption: None, CharacterEllipsis or WordEllipsis.
TextAlignmentHorizontal caption alignment: Left, Center or Right.
FontFont as Family|Size or Family|Size|Regular/Bold|Normal/Italic, size 6–96 DIP. Empty uses the theme font; System uses the theme family.
ForeColorText color as #RRGGBB. Empty uses the current macOS theme color.
BackColorBackground color as #RRGGBB. Empty uses the current macOS theme color.
MarginExternal spacing as one non-negative DIP value or Left,Top,Right,Bottom.
CursorPointer shown over the control: Default, Arrow, Hand, IBeam, Cross, Wait, Help, SizeAll, SizeNS, SizeWE, SizeNWSE, SizeNESW or NotAllowed.
OpacityVisual opacity from 0 (transparent) to 1 (opaque).
Range: 0 to 1.
DesignLockedPrevents movement and resizing in the Designer without changing runtime interaction.
AccessibleDescriptionAdditional help text announced by assistive technology.
AutomationIdStable automation identifier; empty uses the component Name.
AlignmentCanonical horizontal caption alignment: Left, Center or Right. TextAlignment remains a compatibility alias.
AccessibleNameName announced by assistive technology. Empty uses the stable control Name.
AccessibleRoleAccessibility role override. Auto preserves the native semantic role; explicit values use the corresponding platform automation role.
ToolTipTextHelp text shown when the pointer rests over the running control; empty disables the tooltip.
TagApplication-defined text associated with this control; McBasic™ does not interpret it.
AutoSizeAt run time, sizes the Label to its Caption whenever the Caption, Font or WordWrap changes. With WordWrap the width is kept and the height grows. The designer keeps the authored frame.
BorderStyleNone or Solid (a thin gray frame). VB6 FixedSingle is Solid.
IndexPosition 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.
Replace control with the object’s Name when creating a handler. ByRef arguments may be changed by your handler; ByVal arguments report an input value.
