TTMSFNCDataGridConditionalFormatting.EvaluateCellAppearance Method

Main entry point for the appearance pass. Applies every enabled, matching, non-overlay rule to for the given cell, honouring TTMSFNCDataGridFormatRuleItem.Priority and TTMSFNCDataGridFormatRuleItem.StopIfTrue.

API unit family: TMSFNCDataGridConditionalFormatting Declaring type: TTMSFNCDataGridConditionalFormatting

Syntax

function EvaluateCellAppearance(const AProvider: ITMSFNCDataGridFormatProvider; AColumn, ARow: Integer; ALayout: TTMSFNCDataGridCellLayout): Boolean;

Remarks

Rules run from the lowest Priority upwards and each claims the appearance aspects it sets, so the highest-priority match owns an aspect and lower-priority rules only contribute the aspects still free. A rule can therefore match without changing anything when every aspect it sets is already owned. Call from the renderer's cell configuration step, after the layout is set and before any further layout callback.

Parameters

Name	Description
AProvider	The grid-data provider used to read cell values and statistics.
AColumn	Zero-based column index of the cell being evaluated.
ARow	Zero-based row index of the cell being evaluated.
ALayout	The cell layout to merge matching rules' appearance into.

Returns

True if at least one rule matched the cell.
