详细说明： The history of the EhLib library -------------------------------- Version 6.1 + A new component TDBVertGridEh - DataSet Grid with the Vertical Orientation. The component is used to display and edi t a single record of DataSet in a vertical orientation. B asic properties of the TDBVertGridEh: Rows: TDBVerGridRows - A collection of items of TFieldRowEh type to display fields of a record. This is analogous to the Columns collection in TDBGridEh. Options: TDBVHGridOptions - Configure basic properties of the vertical grid. RowsDefValues: TFieldRowDefValuesEh - default values for line Grid row - TFieldRowEh. This is analogous of ColumnDefValues in TDBGridEh. GridLineParams: TDBVertGridLineParamsEh - Color settings of the dividing lines in vertical grid. DataColParams: TDBVertGridDataColParamsEh - The setting of the column with data. LabelColParams: TDBVertGridLabelColParamEh - The setting of the column with row label. See an example of using TDBVertGridEh in a project: \ Demos \ DBVertGridEh.SimpleDemo \ Project1.dpr compiled project: \ Demos \ Bin \ DBVertGridEh.SimpleDemo.Exe * There are changes in the grids inheritance tree: New inheritance tree is: TCustomControl | - TCustomGridEh | - TCustomDBAxisGridEh | - TCustomDBGridEh | | | - TDBGridEh | - TCustomDBVertGridEh | - TDBVertGridEh * Some constants and procedures are moved from the module DBGridEh to the DBAxisGridsEh. + Added a new global function to display a ObjectInspector-like Form. Use the next procedure to display the ObjectInspector-like Form: procedure ShowObjectInspectorForm ( Component: TObject; // A component to Inspect FormBounds: TRect; // Form Borders NewForm: Boolean = False // Show as a new Form ); This is a simple ObjectInspector that can be used to debug property setting at run-time. See an example that shows how to use ShowObjectInspectorForm here: \ Demos \ ObjectInspectorForm.SimpleDemo \ Project1.dpr compiled project: \ Demos \ Bin \ ObjectInspectorForm.SimpleDemo.Exe In DBGridEh + Added an ability to change the size of RowDetailPanel by mouse at RunTime. New properties in RowDetailPanel: property VertSizing: Boolean - Show an RowDetailPanel Splitter at the buttom of the RowDetailPanel. property MinHeight: Integer - Minimum height of the RowDetailPanel. property MaxHeight: Integer - Maximum height of the RowDetailPanel. property SizingBarBeveled: Boolean - Splitter area has a 3D border. property SizingBarHeight: Integer - The height of the Splitter. + Added an ability to darken gray the grid while the data is loading. See StartLoadingStatus and FinishLoadingStatus methods in the TDBGridEh. See the example that shows this opportunity in a project: \ Demos \ DBGridEh.LoadingStatus \ Project1.dpr compiled project: \ Demos \ Bin \ DBGridEh.LoadingStatus.Exe ...展开收缩
