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:
push dword buf
push dword edit1
call dword [edit_box_set_text]
.........
buf db '111-222-333', 0

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.

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
}
  • 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

  • max - the maximum size of the text (должно быть +2 резервных символа)
  • size - the current length of the text
