Description

ItemHTDrawEx is a procedure used to render HTML-tagged values that include links (HTML Anchors) using a TCanvas drawing area. Parameters for the procedure provide the drawing canvas, clipping rectangle, mouse position, and state information needed to draw the specified HTML-tagged values.
Width indicates the calculated width for the render HTML values in Text.
MouseX and MouseY represent the coordinates for the mouse pointer. The value in MouseOnLink is updated to indicate if the MouseX and MouseY coordinates are currently in an HTML anchor in the rendered values. LinkName is updated to indicate the URL for the HTML Anchor.
Scale indicates the scaling (or zoom) factor for the rendered values. The default value is 100. Use scale to control rendering of relative fonts sizes.
ItemHTDrawEx calls the HTMLDrawTextEx procedure to perform the low-level operations required for the procedure.
Use ItemHTDraw to render HTML-tagged values that do not include links (HTML Anchors) or mouse position information.
