Detailed Description

This may become a little font viewer application, having FontForge as its role model.

This UISceneDemo* implements as a GLEventListener, capable to be used with any GLAutoDrawable.

Notable: The actual GlyphShape created for the glyph-grid Group is reused as-is in the top-right info-box as well as in the TooltipShape.

This is possible only when not modifying the scale or position of the GlyphShape, achieved by simply wrapping it in a Group. The latter gets scaled and translated when dropped into each target Group with a Group.Layout.

This is also good example using GraphUI with a Directed Acyclic Graph (DAG) arrangement.

Member Function Documentation

◆ display()

void com.jogamp.opengl.demos.graph.ui.FontView01.display ( final GLAutoDrawable drawable )

Called by the drawable to initiate OpenGL rendering by the client.

After all GLEventListeners have been notified of a display event, the drawable will swap its buffers if setAutoSwapBufferMode is enabled.

Implements com.jogamp.opengl.GLEventListener.

Definition at line 562 of file FontView01.java.

Here is the call graph for this function:

◆ dispose()

void com.jogamp.opengl.demos.graph.ui.FontView01.dispose ( final GLAutoDrawable drawable )

Notifies the listener to perform the release of all OpenGL resources per GLContext, such as memory buffers and GLSL programs.

Called by the drawable before the OpenGL context is destroyed by an external event, like a reconfiguration of the GLAutoDrawable closing an attached window, but also manually by calling destroy.

Note that this event does not imply the end of life of the application. It could be produced with a followup call to init(GLAutoDrawable) in case the GLContext has been recreated, e.g. due to a pixel configuration change in a multihead environment.

Implements com.jogamp.opengl.GLEventListener.

Here is the call graph for this function:

◆ getMaxGlyphCount()

int com.jogamp.opengl.demos.graph.ui.FontView01.getMaxGlyphCount ( )

Definition at line 261 of file FontView01.java.

◆ getMMPerCell()

float com.jogamp.opengl.demos.graph.ui.FontView01.getMMPerCell ( )

Definition at line 258 of file FontView01.java.

◆ init()

void com.jogamp.opengl.demos.graph.ui.FontView01.init ( final GLAutoDrawable drawable )

Called by the drawable immediately after the OpenGL context is initialized.

Can be used to perform one-time OpenGL initialization per GLContext, such as setup of lights and display lists.

Note that this method may be called more than once if the underlying OpenGL context for the GLAutoDrawable is destroyed and recreated, for example if a GLCanvas is removed from the widget hierarchy and later added again.

Implements com.jogamp.opengl.GLEventListener.

◆ main()

Here is the call graph for this function:

◆ reshape()

void com.jogamp.opengl.demos.graph.ui.FontView01.reshape	(	final GLAutoDrawable	drawable,
		final int	x,
		final int	y,
		final int	width,
		final int	height
	)

Called by the drawable during the first repaint after the component has been resized.

The client can update it's viewport associated data and view volume of the window appropriately.

For efficiency the GL viewport has already been updated via glViewport(x, y, width, height) when this method is called.

Parameters

drawable	the triggering `GLAutoDrawable`
x	lower left corner of the viewport rectangle in pixel units
y	lower left corner of the viewport rectangle in pixel units
width	width of the viewport rectangle in pixel units
height	height of the viewport rectangle in pixel units

Implements com.jogamp.opengl.GLEventListener.

◆ setMaxGlyphCount()

void com.jogamp.opengl.demos.graph.ui.FontView01.setMaxGlyphCount ( final int v )

◆ setMMPerCell()
