Re: [osg-users] Using osgWidget for the first time, some questions
Hi again all,
One other comment I'd like to make about osgWidget. In the header files,
most argument names are removed from method declarations, even
constructors. If I were using a binary version of OSG, all I would have
to go with would be the headers, so the argument names should be there,
otherwise I can't know what the arguments are...
If I see
class OSGWIDGET_EXPORT Label: public Widget
{
public:
META_Object (osgWidget, Label);
Label (const std::string = , const std::string = );
// ...
What are those two strings? One might be the text of the label, but
which one, and what about the other one?
I can understand the desire to shut up warnings about unused arguments,
but perhaps this is being too pro-active? :-)
J-S

[osg-users] Using osgWidget for the first time, some questions
Hello all, hello Jeremy,
I'm using osgWidget for the first time, thinking of using it for a
little addition I'm planning for OSG eventually, and just trying to get
familiar with it. I have a few questions.
First, here's my code:
const unsigned int MASK_2D = 0xF000;
// To be able to pass an osg::Vec4 to a
// setColor(float, float, float, float) method
#define mySetColor(obj, c) (obj-setColor(c.r(), c.g(), c.b(), c.a()))
DebugHUD::DebugHUD(osgViewer::View* view)
{
osg::Vec4 titleBarColor(0, 0, 0.5, 0.5);
osg::Vec4 backgroundColor(0.2, 0.2, 0.7, 0.5);
osgWidget::point_type w = view-getCamera()-getViewport()-width();
osgWidget::point_type h = view-getCamera()-getViewport()-height();
m_windowManager = new osgWidget::WindowManager(view, w, h, MASK_2D);
osgWidget::Frame* frame = osgWidget::Frame::createSimpleFrameFromTheme(
frameTheme,
osgDB::readImageFile(osgWidget/theme-1.png),
300.0f,
300.0f,
osgWidget::Frame::FRAME_ALL
);
frame-setPosition(300,100,0);
osgWidget::Table* table = new osgWidget::Table(table, 1, 1);
osgWidget::Widget* center = new osgWidget::Widget(center, 300.0f,
300.0f);
mySetColor(center, backgroundColor);
center-setAlignVertical(osgWidget::Widget::VA_TOP);// Doesn't work
table-addWidget(center, 0, 0);
frame-setWindow(table);
mySetColor(frame-getBackground(), osg::Vec4(1.0, 1.0, 1.0, 0.0));
mySetColor(frame-getBorder(osgWidget::Frame::BORDER_TOP),
titleBarColor);
mySetColor(frame-getCorner(osgWidget::Frame::CORNER_UPPER_LEFT),
titleBarColor);
mySetColor(frame-getCorner(osgWidget::Frame::CORNER_UPPER_RIGHT),
titleBarColor);
mySetColor(frame-getBorder(osgWidget::Frame::BORDER_LEFT),
backgroundColor);
mySetColor(frame-getBorder(osgWidget::Frame::BORDER_RIGHT),
backgroundColor);
mySetColor(frame-getBorder(osgWidget::Frame::BORDER_BOTTOM),
backgroundColor);
mySetColor(frame-getCorner(osgWidget::Frame::CORNER_LOWER_LEFT),
backgroundColor);
mySetColor(frame-getCorner(osgWidget::Frame::CORNER_LOWER_RIGHT),
backgroundColor);
m_windowManager-addChild(frame);
m_camera = m_windowManager-createParentOrthoCamera();
m_windowManager-resizeAllWindows();
view-getCamera()-addChild(m_camera.get());
view-addEventHandler(new
osgWidget::MouseHandler(m_windowManager.get()));
view-addEventHandler(new
osgWidget::KeyboardHandler(m_windowManager.get()));
view-addEventHandler(new
osgWidget::ResizeHandler(m_windowManager.get(), m_camera.get()));
view-addEventHandler(new
osgWidget::CameraSwitchHandler(m_windowManager.get(), m_camera.get()));
}
So, here are my questions.
1. The widget in the center is not the color I set it to. The alpha
doesn't seem to be taken into account. I'd like my whole window to be a
transparent blue (backgroundColor).
2. When I resize the frame to make it larger (dragging the bottom-right
corner down and to the right for example), I'd like the widget in the
center to resize itself to fit. Is that possible? Well, in fact if I
could do without that widget it would be even better, but I want the
center of the window to be transparent blue, and
getBackground()-setColor() makes the color visible even on the corners
of the window, which I don't want...
3. I want the widgets in my frame to stay at the top of the frame when
it's resized. But even if I set my widget's vertical alignment to
VA_TOP, it doesn't work (see the line with the Doesn't work comment
above). Is that a bug or should I do something else to get what I want?
BTW, to set the vertical alignment I would have expected to call
setVerticalAlignment instead of setAlignVertical, any reason why it's
named that way? setVerticalAlignment seems more natural.
Other than that, it seems that osgWidget will allow me to do what I want
and I'm enjoying working with it (though I'm only doing basic things
right now...).
Thanks in advance,
J-S

Hi Sebastien,
Maybe look at osgwidgetmessagebox example, if i remember it does what
you want.

Hello Cedric, Maybe look at osgwidgetmessagebox example, if i remember it does what you want. That showed me how to make the center widget auto-resize, yes. Thanks. What about the other questions? (the color of the center widget not using the alpha, and the alignment of widgets to the top of the frame) Thanks a lot, J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
