This thread reads from /dev/console and injects the keyboard + input into NX. NX will determine which window is at the top of the + heirarchy and re-direct the keyboard input to only that top window. + This solves an important problem with, for example, running multiple + copies of the NxConsole: On the copy of the NxConsole at the top of + the heirarchy should get the keyboard input. + * UnitTests/nxwm/main.cxx: Now starts the keyboard thread if + CONFIG_NXWM_KEYBOARD is defined. + * NxWM::CTaskbar: After drawing the task bar, need to raise the + application window otherwise the taskbar will be on the top and + keyboard input will not be received by the top application. + * NxWM::CTaskbar: Bugfix... previous window should not be minimized + when a new window is started. It should stay in a maximized state + so that it will re-appear with the window above it is closed or + minimized. + * NxWM::CHexCalculator: Add a hexadecimal/decimal calculator + example. + * NXWidgets::CNxTkWindow: Back out height adjustment in the getSize() + method. The code was correct as it was before. + * NXWidgets::CButtonArray and NXWidgets::CGraphicsPort: There is + a kludge in there to handle the case where we cannot read the + background data because the LCD does not support read operations. + In that case, we just use the default background color. However, + that doesn't work either for the case where the background color + changes when the widget is selected. Then the background color + in the font is wrong. Fixed in CButtonArrary, but the problem + probably exists in other places as well. + * NxWM: Increase default spacing of icons on the Start Window. + * NxWM::CHexCalculator: Fix some non-standard calculator behavior + after = is pressed. Use upper case hex. Increase font size. + * nxwm/Makefile: Fix error that creapt in during some other + recent check-ins. pascal-3.0 2011-05-15 Gregory Nutt <gnutt@nuttx.org> |
