The following parameters are available to set up value editor using binding string:
| Name of the parameter |
Type | Description | Mandatory |
| VALUE | Real | Default value. | None |
| MINVAL | Real | Minimum available value. | None |
| MAXVAL | Real | Maximum available value. | None |
| PRECISION | Integer | Precision of displayed value (number of digits after comma). | None |
| STEP | Real | Step. | None |
| ALLOWEMPTY | Logical | Value can be empty. | None |
| CORRECTONEXIT | Logical | Indicates that value is automatically adjusted on editor loss of focus. | None |
Logical values are set as a character string of the ON/OFF or the True/False type.
None
UI="DecimalEdit" CORRECTONEXIT="True" MAXVAL="100" MINVAL="-100" PRECISION="20" STEP="0.000000000000000000005" VALUE="0"
Executing the example requires a form with the button named Button1 on it, the TabSheetBox component and the UiTabSheet component named UiTabSheet1, which is the data source for TabSheetBox.
Class TestForm: Form
Button1: Button;
UiTabSheet1: UiTabSheet;
TabSheetBox1: TabSheetBox;
Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
BM: IBindingManager;
DecimalEditBinding: IBindingDecimalEdit;
Begin
BM := New BindingManager.Create;
DecimalEditBinding := BM.CreateByUi("DecimalEdit") As IBindingDecimalEdit;
DecimalEditBinding.MinValue := -100;
DecimalEditBinding.MaxValue := 100;
DecimalEditBinding.Precision := 20;
DecimalEditBinding.Step_ := 0.000000000000000000005;
DecimalEditBinding.Value := 0;
DecimalEditBinding.CorrectOnExit := True;
UiTabSheet1.TabSheet.Cell(0, 0).Style.Binding := DecimalEditBinding.AsString;
End Sub Button1OnClick;
End Class TestForm;
On clicking the button the high-precision value editor will be determined for the A0 table cell. On editing the cell, real value input field is displayed, minimum value is -100, maximum value is 100, precision is 20 digits after point, step is 0.000000000000000000005, the default value is 0.
