Welcome to the README for GUI LIBRARY FOR KOLIBRIOS IN C. |
This library tries to use the wealth of code already written for KolibriOS in assembly. |
The files currently available are : |
0) loadboxlib.asm : |
This is a wrapper created so that C can call assembly functions. |
Assemble this to loadboxlib.obj and use with cross compiler linker the .obj file |
to create correct executables which use this GUI library. |
1) kolibri_boxlib.h : |
This file contains functions for initializing boxlib from C. This is used by the |
function kolibri_gui_init() in kolibri_gui.h |
2)kolibri_button.h: |
This file contains functions to create and use kolibriOS buttons. |
3)kolibri_checkbox.h: |
This file contains functions to create and use Check boxes from BOXLIB. |
4)kolibri_editbox.h: |
This file contains functions for creating text boxes (edit boxes from Boxlib) |
5)kolibri_colors.h: |
This file has functions to initialize global kolibri color table |
so that the GUI can use colors from the System theme. |
6)kolibri_gui_elements.h: |
This defines generic containers for GUI elements so that ANY element |
(buttons, editboxes, checkboxes, etc) can have their redraw/mouse/key event |
functions. This helps create a list of all the elements and draw them together. |
ALL FILES ABOVE ARE INCLUDED IN KOLIBRI_GUI.H SO THEY DO NOT NEED TO BE INCLUDED IN THE CODE YOU WRITE. |
7)kolibri_gui.h: |
This is the master file we use. This baby contains everything you need (all GUI elements are included). |
This also contains event handlers that can be simply called from the main application loop. |
This will make your life easy on KolibriOS ;) USE IT! |
The function kolibri_gui_init() needs to be called from all applications using this library. |
8)boardmsg.c: |
Sample application written to show off the library. |
This application sends messages to Debug Board on KolibriOS. |
Enter a msg and press the button with the mouse to send messages! |
This is the first of many applications to come with this library. |

NOTES |
Refer to boardmsg.c to see how the library is used. |
Use instructions from here to build files in C : http://board.kolibrios.org/viewtopic.php?f=24&t=3117 |

Suggestions, Feedback and Ideas are welcome and appreciated! |
Please contact : ashmew2 (on board.kolibrios.org) or ashmew2 at gmail dot com for discussing, |
Or post on : http://board.kolibrios.org/viewtopic.php?f=24&t=3117#p62536 so that everyone can participate! |

USE .section '.init' code for writing loader asm C mixed code (in FASM) |
Got to know this by checking out the linker script on KGCC. -Xlinker -verbose . |
Inside the .text section that is being assembled, the .init is placed at the very beginning. |
Let the macros expand, GCC simply places .init on the top and therefore it works. |
Inexplicable errors if .init is not used and .text or .flat is used... Took 4 hours to figure out. |
