LinkListControlToField¶

Qualified name: delphivcl.LinkListControlToField

class LinkListControlToField¶

Bases: CustomLinkListControlToField

Links a list control to a field. The TLinkListControlToField class extends TCustomLinkListControlToField with published properties.

Tip: If the direction is bidirectional, then the control must support the IEditLinkObserver interface.

Type:: bool

BindMethodsToEvents(prefix)¶: Connects methods to component events if they are named using the following pattern: Prefix_ComponentName_EventName. Example: def handle_button1_OnClick(Sender): pass The function returns a list of tuples. Each tuple contains the name of the component, the name of the event and the method object assigned to the event. Note that the prefix parameter is optional and will default to “handle_”.

ComponentCount¶: Returns the owned component count

Components¶: Returns an iterator over the owned components

Control¶

Embarcadero Technologies does not currently have any additional information.

Type:: Component

CustomFormat¶

Embarcadero Technologies does not currently have any additional information.

Type:: str

DataSource¶

Specifies a TBaseLinkingBindSource object to which this delegate component links. Use DataSource to determine or set the TBaseLinkingBindSource object that connects to a specific dataset.

Type:: BaseLinkingBindSource

FieldName¶

Embarcadero Technologies does not currently have any additional information.

Type:: str

FillBreakCustomFormat¶

Specifies a custom expression that is used with the field defined by the FillBreakFieldName property. For instance, the expression StrCopy(%s, 0, 1); causes a break when the first character of the field is different. This property is optional.

Type:: str

FillBreakFieldName¶

Specifies the field used to determine a break. This property is optional.

Type:: str

FillBreakGroups¶

Specifies a collection of break value ranges. The break value falls within an item in this collection. The display value associated with the item is displayed in the header. This property is optional.

Type:: FillBreakGroups

FillExpressions¶

Specifies additional optional expressions to use when filling the list control. Use this collection when multiple expressions are needed to fill an item in the list. For instance, you can use FillExpressions in order to populate a FireMonkey list box item Text and Detail properties. Use the FillDisplayCustomFormat and FillDisplayCustomFormat properties in order to fill the Text property and add an item to the FillExpressions collection, for the Detail property.

Type:: FormatExpressions

FillHeaderCustomFormat¶

Specifies a custom expression that is used with the field defined by the FillHeaderFieldName property. For instance, the expression StrCopy(%s, 0, 1); displays the first character of the field in the header. This property is optional.

Type:: str

FillHeaderExpressions¶

Specifies a collection of expressions to fill a list header. This property is optional.

Type:: FormatExpressions

FillHeaderFieldName¶

Specifies the field to display in the list header. If FillBreakFieldName and FillBreakCustomFormat are blank, then the value determined using FillHeaderFieldName and FillBreakCustomFormat controls breaks. This is the only required field to cause breaking.

Type:: str

GetParentComponent()¶: Returns the parent of a component.

HasParent()¶: Indicates whether the component has a parent to handle its filing.

ListItemStyle¶

Embarcadero Technologies does not currently have any additional information.
