(I'll omit osgWidget namespace from now on). It seems to me that there
are some inconsistency in the code. In Style there are multiple
applyStyle method overloads, applying style for different
widgets/windows built-in in osgWidget. Plus you can do overrides. It's
good so far.
The problem lies in StyleManager::_applyStyleToObject (which calls
_coearceAndApply, which calls _applySpecificStyle, which calls
Style::applyStyle). With current implementation Style::applyStyle
variants for Input, Window, Frame::Corner, Frame::Border,
Window::EmbeddedWindow are never called, because their classes' names
are omitted in methods' if/else if block, making it impossible to use
styles with most than half of built-in widget/window types.
My fix simply adds couple else if blocks, making each
Style::applyStyle variant callable. By the way, I think that next
update should add Style::applyStyle overload for Table class and add
proper className overloads for Input and Window."
SETUP_EXE, in order to have a unique entry point to build the
libraries. With this changes the android integration will be less
painful (currently is a big IF(ANDROID) for each CMakeLists.txt) and
more maintainable in the future. I hope next submissions will be for
supporting android from my colleague Jorge.

The current setAnchorHorizontal() command doesn't center the center of the object, it just center's the object's origin. The following change to osgWidget::Window::update() will correct that behavior so that it is consistent with setAnchorVertical() behavior.

hpux. I have skipped irix this time as irix is too dead to keep osg building
there.
As usual, solaris does not like member templates in stl containers.
Some headers missing and link problems due to missing libraries."
osgWidget::Input:
[Functional changes]
- Previously, the field would be filled with spaces up to its max length, and typing would just replace the spaces. Also, there was a _textLength variable that kept track of the real length of text in the field, since the osgText::Text's length just reflected the length of spaces+text entered. This was not great, as you could still select the spaces with the mouse and it just feels hacky. So I changed it to only contain the text entered, no spaces, and _textLength was removed since it's now redundant (the osgText::Text's length is used instead).
- Fixed the selection size which (visually only) showed one more character selected than what was really selected.
- Fixed selection by dragging the mouse, it would sometimes not select the last character of the string.
- Cursor will now accurately reflect whether insert mode is activated (block cursor) or we're in normal mode (line cursor) like in most editors.
- Implemented Ctrl-X (cut)
- Added a new clear() method that allows the field to be emptied correctly. Useful for a command line interface, for example (hint, hint).
- Mouse and keyboard event handler methods would always return false, which meant selecting with the mouse would also rotate the trackball, and typing an 's' would turn on stats.
[Code cleanup]
- Renamed the (local) _selectionMin and _selectionMax variables which are used in a lot of places, as the underscores would lead to think they were members. Either I called them selection{Min|Max} or delete{Min|Max} where it made more sense.
- Fixed some indenting which was at 3 spaces (inconsistently), I'm sure I didn't catch all the lines where this was the case though.
- Put spaces between variable, operator and value where missing, especially in for()s. Again I only did this where I made changes, there are probably others left.
The result is that delete, backspace, Ctrl-X, Ctrl-C, Ctrl-V, and typing behaviour should now be consistent with text editor conventions, whether insert mode is enabled or not. I hope. :-)
Note, there's a nasty const_cast in there. Why isn't osgText::Font::getGlyph() declared const?
Also, as a note, the current implementation of cut, copy and paste (in addition to being Windows only, yuck) gets and puts the data into an std::string, thus if the osgText::String in the field contains unicode characters I think it won't work correctly. Perhaps someone could implement a proper clipboard class that would be cross-platform and support osgText::String (more precisely other languages like Chinese) correctly? Cut, copy and paste are not critical to what I'm doing so I won't invest the time to do that, but I just thought I'd mention it.

of an osgWidget::Label with an osgText::String. I had to do this on a
project I'm working on, because I needed UTF-8 strings on my labels,
and using setLabel with std::string was not working.

Also, there was also a small bug in osgDB's CMakeLists.txt that was causing an error when I tested with CMake 2.4.4.
IF(${OSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX} STREQUAL "quicktime")
was changed to

1. In WindowManager.cpp childRemoved method the second parameter "end" is misleading and
should be named "numChildren" instead. It represents how many children to remove. As a result, the method was implemented incorrectly and failed to remove UI objects. So I fixed it.
replaced this:
void WindowManager::childRemoved(unsigned int start, unsigned int end) {
while(start < end) {
Window* window = getByIndex(start);
if(!window) continue;
if(_remove(window)) {
window->_index = -1;
window->unmanaged(this);
}
start++;
}
}
with this:
void WindowManager::childRemoved(unsigned int start, unsigned int numChildren) {
for (unsigned int i = start; i < start+numChildren; i++)
{
Window* window = getByIndex(i);
if(!window) continue;
if(_remove(window)) {
window->_index = -1;
window->unmanaged(this);
}
}
}
2. in Input.cpp
The cursor in Input did not get positioned correctly, probably as a left over from the TOP LEFT origin system which is now BOTTOM LEFT.
in method positioned()
replaced this:
_cursor->setOrigin(x + xoffset + 1.0f, y - _cursor->getHeight() + 1.0f);
with this:
_cursor->setOrigin(x + xoffset + 1.0f, y + 1.0f);
Now it is placed correctly.
"
if(
(!win || win->getVisibilityMode() == Window::VM_PARTIAL) &&
!win->isPointerXYWithinVisible(x, y)
) continue;
But it probably should be
if (!win || (win->getVisibilityMode() == Window::VM_PARTIAL) && !win->isPointerXYWithinVisible(x, y)))
continue;
The effect of the bug is to segfault if a non-osgWidgets::Window node hasn't been excluded from picking via NodeMask."
when applying styles to a Label element the code below runs in a infinite loop.
The reason for this is that nothing increments the Reader "r" in the case when applying a style to label,
so I advance the reader when no match was found.
( To replicate the error apply style to any label)
replaced this:
while(!r.eof()) if(_styles[style]->applyStyle(t, r)) inc = true;
with this:
while(!r.eof())
{
if(_styles[style]->applyStyle(t, r))
inc = true;
else
r.advanceOverCurrentFieldOrBlock();
}
I tested it and it works well for me, I did not find any problems with it.
2. Added style support for Canvas element, event though there is no styles to apply yet.
It is usefull for someone who inherits from Canvas class to develop another element.
If applyStyle(Canvas) does not exist
there is no way to apply style to the element that inherited from Canvas element.
Added virtual
bool applyStyle(Canvas).
and in added call to apply style if the Object is of type Canvas:
StyleManager::_applyStyleToObject(osg::Object* obj, const std::string& style) {
...
else if(!std::string("Canvas").compare(c))
return _coerceAndApply<Canvas>(obj,style,c);
