DBGrid DeLuxe

Properties (details):

Types are mentioned, if not yet obvious by the property's name.

Aside from the properties listed below DBGrid DeLuxe owns all the properties of TDBGrid. Special 32 bit features like TColumns and Multiselect are fully supported!

(*: Published and/or modified properties of T(Custom)DBGrid.)

public

• * Canvas
• * Col
• * ColCount
• * EditorMode
• * InplaceEditor
• InplaceMemo: TInplaceMemoEditor
  Memofield editor. Its properties can either be configured using StyleMemo, or be read and altered at runtime. At runtime all of its properties (like TMemo) can be addressed.
• * Row
• * RowCount

published

• * FixedColor
  Color of indicator column.
• FixedDataColor
  Color of fixed data columns.
• FixedDataCols: Integer
  Number of fixed data columns.
• FixedDataFont
  Font of fixed data columns.
• IndicatorColor
  Color of  indicator symbols.
• OptionsDP: set of (dpColMoving, dpFixedVertLine, dpFixedHorzLine, dpRowSizing, dp3DFixedDataCols dpEnterFixedDataCols, dpMoveFixedDataCols)
  dpColMoving, dpFixedVertLine, dpFixedHorzLine, dpRowSizing: Important reactivated properties, as known from StringGrids. We adapted them to the changed requirements of a DBGrid and the DeLuxe extensions.
  dp3DFixedDataCols: Fixed data columns can appear in the 3D look of the other fixed areas or in the 2D look of ordinary data cells.
  dpEnterFixedDataCols: Fixed may optionally be entered, if they are at their default index position. They are locked only when shown in a horizontally scrolled grid. At their default position they may be entered and during this they change to ordinary data cells. If this Option is not set, fixed data cells are always locked.
  dpMoveFixedDataCols: Moreover, it may be wanted or not that an entered fixed data column can be exchanged by column movements.
• RowHeight
  Row height of data cells. Important for multiline output, e.g. of memofields, but also other field types with their Wordwrap property set.
  If dpRowSizing is set, RowHeight can be adjusted in the grid.
• * TitleColor
  Default background color of the title row.
• * TitleFont
  Default font of the title row.
• TitleHeight
  Height of the title row. Allows multiline titles with wordwrapping.
• StartField
  Field, which will be selected when creating the grid.
• StyleBoolean
  • SwitchMode: (swStandard, swStandardOrClick)
    For boolean fields one can choose between the known and an additionally mouse sensitive behavior: As usual, a first click opens the editor, if not already active. A single click within the open editor toggles the field value (and its text output). A double click does the same without opening the editor.
• StyleMemo
  • EditorActive: Boolean
    Only at EditorActive the memo editor is used. Otherwise any editor (also the default field editor!) is suppressed in memo fields.
  • EditorMaxLength: Integer
    Number of characters for input limit. 0 = only system limits.
  • EditorScrollbars: TScrollStyle
    The scrollbars to be shown.
  • EditorStartPos: (spAutoSelect, spTop, spBottom, spClick)
    If the memo editor is started by mouse click, F2 or typed characters, it can be determined, wether the cursor shall be placed on top or end of the text or at the current mouse position. Also an AutoSelect (select all, end of text) can be chosen.
  • ShowMode: (smData, smText)
    As table output can be shown either the content (smData) of memofields or stored text.
  • TextOnData: String
    Output text, if the memofield contains data.
  • TextOnNull: String
    Output text, if the memofield is empty.
  • WordWrap: Boolean
    Wordwrap for output and editor.
• StyleString
  • WordWrap: Boolean
    Wordwrap for output.
• WordWrap: Boolean
  Wordwrap for the output of other text based field types. With the ability of multiline data output it may be wanted to force an uncut output for the other field types.
  Hint: It is possible and especially useful for field style related properties to make dynamical changes at runtime (e.g. on column events).

New events:

• OnDrawTitleCell
  Drawing of a title cell can be programmed like for data cells.
• OnRowExit/Enter
  Triggered when the old and the new data row accomodate to record movements.

New public methods:

• function ColOffset: Integer
  Number of fixed Columns without data output (=indicator).
• function ColField(ACol: Integer): TField
  The field of a column.
• procedure ShowMemo
  Showing the MemoEditor.
• procedure HideMemo
  Hiding the MemoEditor.

Ancestor bugs/misbehavior fixed:

• Stable ressources each time destroyed.
• FixedColor works (for indicator column), v. TitleColor.
• No InplaceEditor in MemoFields, causing errors. Now output-only (with scrolling) or new InplaceMemoEditor.

TInplaceMemoEditor:

• Descendant of TCustomMemo.
• Public and published properties equal TMemo.
