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

OCPNMessageBox()

int OCPNMessageBox	(	wxWindow *	parent,
		const wxString &	message,
		const wxString &	caption,
		int	style,
		int	timeout_sec,
		int	x,
		int	y
	)

Variable Documentation

g_bresponsive

bool g_bresponsive

extern

Flag to control adaptive UI scaling.

When true, OpenCPN will automatically maximize the application window if the pixel density suggests a touch-friendly device.

This helps ensure better usability on mobile and tablet devices by providing a full-screen interface optimized for touch interaction.

Note

For the most part, the use of this feature is conditionally compiled for Android builds only.
