From Jean-Sebastien Guay, "osgWidget::WindowManager did nothing in its keyUp event, and in particular didn't call any callbacks. Since I wanted to have callbacks on keyUp, I copied what it does on keyDown, which works for me. I could have just used keyDown and saved myself the trouble, but you know me... :-) 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. "

From Jean-Sebastien Guay, "osgWidget::WindowManager did nothing in its keyUp event, and in particular didn't call any callbacks. Since I wanted to have callbacks on keyUp, I copied what it does on keyDown, which works for me. I could have just used keyDown and saved myself the trouble, but you know me... :-) 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.

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. "
