OEDrawSVGToggleTextΒΆ

bool OEDrawSVGToggleText(OE2DMolDisplay &disp, OE2DAtomDisplay *adisp,
                        const std::string &text, const OEFont &font)

bool OEDrawSVGToggleText(OE2DMolDisplay &disp, OE2DBondDisplay *bdisp,
                        const std::string &text, const OEFont &font)

Creates and interactive effect in .svg images. The given text will appear / disappear when clicking at the position defined by the given atom / bond display.

Note

This functionality is only available for .svg image format. In other image formats it has no effects.

The generated svg image should be included into and HTML page with the SVG MIME type.
