Box lib editbox

Introduction

Text field is used when entering text/numeric information.

Functions

• edit_box_key - this function should be called when you enter the information from the keyboard
• edit_box_mouse - this function should be called when you enter the information from the mouse
• edit_box_draw - this function should be called when redrawing.
• edit_box_set_text - it copies the text from the cursor in the text box. If the text in the index is longer than allowed in edit_box element, it is written not all. After calling this function, you need to redraw the window function edit_box_draw, otherwise the changes are not immediately visible. Example of use:

<syntaxhighlight lang="asm">push dword buf push dword edit1 call dword [edit_box_set_text] ......... buf db '111-222-333', 0</syntaxhighlight> where edit1 - edit_box structure element; buf - buffer, which contains the text of the installed.

• version_ed - version element

editbox structure

editbox structure size is set within box_lib.mac file in ed_struc_size parameter. <syntaxhighlight lang="asm">struc edit_box width,left,top,color,shift_color,focus_border_color,\

      blur_border_color,text_color,max,text,mouse_variable,flags,size,pos

{ .width dd width .left dd left .top dd top .color dd color .shift_color dd shift_color .focus_border_color dd focus_border_color .blur_border_color dd blur_border_color .text_color dd text_color .max dd max .text dd text .mouse_variable dd mouse_variable .flags dd flags+0 .size dd size+0 .pos dd pos+0 .offset dd 0 .cl_curs_x dd 0 .cl_curs_y dd 0 .shift dd 0 .shift_old dd 0 }</syntaxhighlight>

• width - width of the element
• left - the left margin
• top - the top margin
• color - background color
• shift_color - color selection by holding [Shift] or mouse
• focus_border_color - frame color when the field is in focus
• blur_border_color - frame color when the field is not in focus
• text_color
• max - the maximum size of the text (должно быть +2 резервных символа)
• size - the current length of the text
