The title of a XPopup can be set using the functions
void fl_setpup_title(int popup_id, const char *title); void fl_setpup_title_f(int popup_id, const char *fmt, ...);
They only differ in the way the new title is passed to the function,
the first one accepts a simple string while the second expects a
format string as used for printf()
etc., followed by the
appropriate number of (unspecified) arguments.
Use the following routines to modify the default popup font style, font size and border width:
int fl_setpup_default_fontsize(int size); int fl_setpup_default_fontstyle(int style); int fl_setpup_default_bw(int bw);
The functions return the old size, style or border width value, respectively.
All XPopups by default use a right arrow cursor. To change the default cursor, use
Cursor fl_setpup_default_cursor(int cursor);
where you can use for cursor
any of the standard cursors
defined in <X11/cursorfont.h>
like XC_watch
etc.
The function returns the previously cursor.
To change the cursor of a particular XPopup only , use the following routine
Cursor fl_setpup_cursor(int popup_id, int cursor);
For example, after the following sequence,
id = fl_defpup(win, "item1|item2"); fl_setpup_cursor(id, XC_hand2);
the popup with ID id
will use a "hand" instead of the default
arrow cursor.
In versions before 1.0.91 XPopups were drawn with a heavy shadow around the box. Drawing of this shadow could be controlled via
void fl_setpup_shadow(int popup_id, int yes_no);
Nowadays this function still exists for backward-compatibility but does nothing.
The appearance of XPopups (and their associated sub-popups) can be change by the following routines:
void fl_setpup_bw(int popup_id, int bw); void fl_setpup_softedge(int pupup_id, int yes_no);
The first sets the border width for a XPopup. Calling
fl_setpup_softedge()
with a true argument for
yes_no
has the same effect as using a negative border width
while using a false (0) argument is equivalent to using a positive one
(so this function isn’t very useful).
The background color and text color of a popup can be changed using
void fl_setpup_default_color(FL_COLOR bgcolor, FL_COLOR tcolor);
By default, the background color bgcolor
is FL_COL1
and
the text color tcolor
is FL_BLACK
.
For "binary" or radio items, that have check box associated with them,
the "checked" or "pushed" color (default is FL_BLUE
) can be
changed with the following routine
void fl_setpup_default_checkcolor(FL_COLOR checkcolor);
There is by default a limit of 32 XPopups per process. To enlarge the number of XPopups allowed, use the following routine
int fl_setpup_maxpups(int new_max);
The function returns the previous limit.
It is possible to use XPopups as a message facility using the following routines
void fl_showpup(int popup_id); void fl_hidepup(int popup_id);
No interaction takes place with a XPopup shown by
fl_showpup()
and it can only be removed from the screen
programmatically via fl_hidepup()
.
