[ngl-devel] New features and a few changes

[Peter R. Brinkler]

Hi,
Since we (the moonlight 3d developers) have now decided to try to make 
the ui for next gen moonlight 3D using nui/ngl I have a few feature 
requests, most are for functionality which is essential for various 
components of a 3d modeling application as well as many other types of 
applications. Some maight already be planned or present in some form.

1: A border widget which creates a border around the contents. With the 
ability to specify the border using a set of svg for the various border 
posisions (corner, edge....) .

2: The ability to exclude any number of the subwidgets of nuiWidgetBox 
from the scaling of the contents. This is important to our project, 
which includes fairly complex interface, where resize must allow the 
labels and text to remain same size.

3: n-way paned widget, for the viewport. Fltk (www.fltk.org) provides 
such a widget which may serve as inspiration to the implementor.

4: Tabbed container.

5: Scrolled container for adding scrollbars around children.

6: Choice widget.

7: Value widgets:
class Value;
+ class InputValue : public Value; // Single line input, with up/down 
arrows to manipulate value with mouse. Should include precision, range, 
step...
 + class InputDoubleValue : public Value;
 + class InputStringValue : public Value
 + class InputLongValue : public Value
+ class SliderValue : public Value; // With range, precision, step and 
current value indicated.
 + class Dial : public SliderValue; // Knobs and such.
 + class Wheel : public SliderValue; // Those sgi wheels
 + class ProgressBar : public SliderValue;

8: Ability to modify the colours (background, border, etc) of the 
widgets using this->SetColour( 0xff00aaff );

9: Form widget like the one motif defines. The form widget allows:
  Ability to specify resizability.
 Ability to specify positions of child widget borders as well as 
relatively to other child widgets.
  Ability to lock child widgets borders to edge of container as well as 
other child widget borders including the ability to lock border 
positions ( never scale this widget so the border is moved )

10: Ability to specify animation for button press, menu opening etc. events.

11: The ability to specify the images for widgets using svg.

12: Colour chooser widget

13: Ramp widget - A widget which creates a ramp between one or more colours:
|+| <- 0xff0000ff
| |
| | <- colour here is interpolated
| |    between 0xff0000ff and 0x00ff0044 including interpolation in the 
alpha channel
| |
|+| <- 0x00ff0044
The ability to obtain the colour under the cursor when mouse is sclicked 
on the widget. This widget could be used in the colour chooser.

14: A RAD tool.

15: A tutorial into how to write a custom widget.

16: Demos for each type of functionality/Widget

More to come......

Sincerely,
