Description
Use AsInteger to Read/Write the Integer Value. ThousandSeparators can control the output, Thousand Separators are ignored in input.

Sign Toggling means if a '+' is pressed then it is displayed, and if pressed again it disappears. If Sign Toggling is disabled ShowPosSign can be set to show '+' signs

BlankWhenZero displays a Blank Field when the value is Zero.

ZeroPad is used with MaxLength (can't be 0) to fill the field to the left with Zeroes.

Edit Control also has Alignment and ReadOnly Color Changing. Includes Bounds Validation.

Flat controls whether the control has a MS Office 97/2000 type behaviour, where the "look" changes when the control has focus or the mouse passes over it. ColorBorderFocus & ColorBorderUnfocus are used for Border colors when the Control is Flat.

OnMouseEnter & OnMouseExit - allow you to set up your own "hot" controls if the Flat look'n'feel is not what you are after.

Null allows an edit field to be marked as having no proper value, and it will then display whatever NullStr is set to. Ctrl-N is the Keyboard entry for Null if AllowKbdNull is true. OnNullEvent is called when the Keyboard entry of Null is permitted.

ColorRW replaces the normal Color Property of Standard Edit Controls.

By default Read Only fields will be shown in a different Color, to disable this set ColorRW and ColorRO to the same, eg clWindow. clBtnFace is often a better choice for ColorRO on older Video Cards and older Notebooks

ColorFocus can be used so that the Color of the edit field changes when it receives focus (provided it is not ReadOnly). To use this feature ColorFocus must be set to a different value than ColorRW but beware the various Color combinations that result.

ColorDisabled controls the Color of the Control when Disabled, ie Enabled := False.

If ESBEnterAsTab is true then the Enter Key will be treated as though it were the Tab Key.

If ESBEscAsUndo is true then the Esc Key will be cause an Undo to occur in the field.

If ESBArrowsAsTab is true then Up Arrow will move to previous field like Shift-Tab, and Down Arrow will move to next field like Tab.
