CustomGrid#

Qualified name: delphivcl.CustomGrid

class CustomGrid#

Bases: CustomControl

TCustomGrid is the base type for all components that present information in a two-dimensional grid. Use TCustomGrid as a base class when defining components that represent information in a tabular format. TCustomGrid introduces properties and methods to control the appearance and behavior of the grid, including responses to mouse actions and user editing. Do not create instances of TCustomGrid. Instead, put a grid control in a form by instantiating a descendant of TCustomGrid. Use TDrawGrid to represent non-textual material in a tabular grid. For text, use a TStringGrid object. If the text represents field values from a dataset, use TDBGrid.

BeginUpdate()#: Embarcadero Technologies does not currently have any additional information.

CanFocus()#: Indicates whether a control can receive focus.

ControlCount#: Returns the count of contained controls

Controls#: Returns an iterator over contained controls

Create(AOwner: Component)#: Creates an instance of TCustomGrid. Call Create to create a grid control at runtime. Grid controls placed on a form at design time are created automatically. Owner is a component that is responsible for freeing the grid and for initiating the streaming process when it is saved to a form file.

Destroy()#: Destroys an instance of TCustomGrid. Do not call Destroy directly in an application. Instead, call Free. Free verifies that the grid reference is not nil, and only then calls Destroy.

EndUpdate()#: Embarcadero Technologies does not currently have any additional information.

Focused#: Determines whether the control has input focus.

Handle#: Provides access to the underlying Windows screen object for the control.

HandleAllocated#: Reports whether a screen object handle exists for the control.

IsUpdating#: Embarcadero Technologies does not currently have any additional information.

MouseCoord(X: Integer, Y: Integer) → GridCoord#: Returns the row and column indexes of the cell that contains a point specified in screen coordinates. Call MouseCoord to locate the column and row of the cell which contains a given screen coordinate. Usually, MouseCoord is used to locate the cell that is under the mouse.

ParentWindow#: Reference to parent’s underlying control.

SetFocus()#: Gives the input focus to the control.

Showing#: Indicates whether the control is showing on the screen.

TabStop#

Determines whether the user can tab to a control. Use the TabStop to allow or disallow access to the control using the Tab key. If TabStop is True, the control is in the tab order. If TabStop is False, the control is not in the tab order and the user cannot press the TAB key to move to the control.

Note: TabStop is not meaningful for a form unless the form assigns another form to be its parent.

TextWidthToColWidth(ATextLength: Integer, ACaption: string, AColumnObj: Object) → Integer#: Embarcadero Technologies does not currently have any additional information.
