Frame

Use a captioned container to explain related input fields.

41 properties12 events0 methods

Use it in a Form#

A Frame is both a parent and a visual label for its group. The group caption should explain the relationship between the fields. Keep it short enough to remain readable when resized, and verify that children truly belong to the Frame.

Add Frame to its intended parent and name it fraMain for this example:

PropertyExample value
Caption"Customer details"

Properties#

Contract defaults are shown below. Where a new control has a different Designer starting value, that value is listed separately.

DoubleDefault: 0

Horizontal position in device-independent points, relative to the parent container.

Range: -100000 to 100000.

Top

DoubleDefault: 0

Vertical position in device-independent points, relative to the parent container.

MinWidth

DoubleDefault: 0

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

Range: 0 to 100000.

MinHeight

DoubleDefault: 0

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

Range: 0 to 100000.

TabIndex

LongDefault: 0

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

ZIndex

LongDefault: 0

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

Range: -100000 to 100000.

Anchor

StringDefault: "Left,Top"Not in InspectorNot serialized

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

StringDefault: "None"

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

Margin

StringDefault: "0"

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

Visible

BooleanDefault: True

Whether the frame is shown in the running application.

Enabled

BooleanDefault: True

Whether children in the frame accept user interaction.

HitTestVisible

BooleanDefault: True

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

AllowDrop

BooleanDefault: False

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

DragMode

LongDefault: 0

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

StringDefault: ""

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.

Font

StringDefault: ""

Container caption font as Family|Size or Family|Size|Regular/Bold|Normal/Italic, size 6–96 DIP. Empty uses the default caption font.

ForeColor

StringDefault: ""

Container caption text color as #RRGGBB. Empty uses the current theme color.

BackColor

StringDefault: ""

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

BorderStyle

StringDefault: "Solid"

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

BorderColor

StringDefault: ""

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

BorderWidth

DoubleDefault: 1

Container border width in device-independent points.

Range: 0 to 100.

CornerRadius

DoubleDefault: 0

Container corner radius in device-independent points.

Range: 0 to 1000.

AccessibleName

StringDefault: ""

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

Cursor

StringDefault: "Default"

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

Opacity

DoubleDefault: 1

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

Range: 0 to 1.

DesignLocked

BooleanDefault: FalseDesigner only

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

AccessibleDescription

StringDefault: ""

Additional help text announced by assistive technology.

AccessibleRole

StringDefault: "Auto"

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

AutomationId

StringDefault: ""

Stable automation identifier; empty uses the component Name.

ToolTipText

StringDefault: ""

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

Tag

StringDefault: ""

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

Caption

StringDefault: ""

Optional caption displayed in the frame chrome.

Designer starting value: "Frame".

WordWrap

BooleanDefault: False

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

TextTrimming

StringDefault: "None"

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

Padding

StringDefault: "8"

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

Designer starting value: 8.

ClipToBounds

BooleanDefault: True

Whether authored child content is clipped to the container bounds.

Index

LongDefault: -1Read only in BASICDesigner Index row

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.

Events and parameters#

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.
