Function Documentation

GetOCPNGUIScaledFont()

wxFont GetOCPNGUIScaledFont

(

wxString

item

)

Retrieves a font optimized for touch and high-resolution interfaces.

Generates a font specifically tuned for responsive and touch-friendly interfaces, with more aggressive scaling than standard font methods.

Parameters

item	UI element identifier (e.g., "AISTargetAlert", "StatusBar")

Returns

A wxFont object scaled for touch and high-resolution interfaces

Note

Ensures minimum physical font size for improved readability

Particularly suitable for toolbars, buttons, and touch controls

GetOCPNScaledFont()

wxFont * GetOCPNScaledFont	(	wxString	item,
		int	default_size = 0
	)

Retrieves a font from FontMgr, optionally scaled for physical readability.

Returns a font configured for a specific UI context, scaling based on system settings and preserving readability across different displays.

Parameters

item	UI element identifier (e.g., "AISTargetAlert", "StatusBar")
default_size	Optional base font size in points. 0 uses platform default.

Returns

Pointer to a dynamically scaled wxFont

Note

Font is managed by OpenCPN's central font cache

Pointer is shared and should not be deleted by caller
