The following commands allow you to manipulate the lines in a custom window.
/aline [color] <@name> <text> add line to list /cline [color] <@name> <N> changes the color of the Nth line to color C /dline [color] <@name> <N[-N2]> delete Nth line through N2th line /iline [color] <@name> <N> <text> insert line at Nth line /rline [color] <@name> <N> <text> replace Nth line /sline [color] <@name> <N> select Nth line
Note: These commands only works for custom windows
-s switch selects the line that was just added and clears the current selections. -a switch selects a line without clearing the current selections. -h switch highlights the window's button if it's currently minimized. -p switch forces the line of text to be wrapped if it's too long to fit on one line. -r switch is used with /cline to reset a nickname color in a channel listbox to the default color. -i switch is used with /aline and /iline to indent a newly added line. -n switch is used with /aline and /iline to prevent a line from being added if it exists. -m switch is used with /cline when coloring nicknames in a channel nicklist, and makes mIRC also color the nick in channel messages. -l switch makes the command apply to a side-listbox of a window
Make a custom window @test and add a line "test1" in the default color and another line "test2" in color 3.
window -e @test aline @test test1 aline 3 @test test2
Change the color of line 1 to color 4, and change the color of line 2 to the default color.
cline 4 @test 1 cline @test 2
Insert "test3" between line 1 and 2 in color 5. Since line 6 doesn't exist, the second command just adds the line "test4" to the window, like /aline.
iline 5 @test 2 test3 iline @test 6 test4
Replace line 2 with "test5", and delete lines 3 and further.
rline @test 2 test5 dline @test 3-
