<H3>Description</H3>
|
|
This widget displays a piece of text. When you set the <TT>value()</TT>
|
|
, <TT>Fl_Output</TT> does a <TT>strcpy()</TT> to it's own storage,
|
|
which is useful for program-generated values. The user may select
|
|
portions of the text using the mouse and paste the contents into other
|
|
fields or programs.
|
|
<CENTER><IMG src=./text.gif></CENTER>
|
|
<P>There is a single subclass, <A href=Fl_Multiline_Output.html#Fl_Multiline_Output>
|
|
Fl_Multiline_Output</A>, which allows you to display multiple lines of
|
|
text. </P>
|
|
<P>The text may contain any characters except \0, and will correctly
|
|
display anything, using ^X notation for unprintable control characters
|
|
and \nnn notation for unprintable characters with the high bit set. It
|
|
assummes the font can draw any characters in the ISO-Latin1 character
|
|
set. </P>

<H4><A name=Fl_Output.Fl_Output>Fl_Output::Fl_Output(int x, int y, int
|
|
w, int h, const char *label = 0)</A></H4>
|
|
Creates a new <TT>Fl_Output</TT> widget using the given position,
|
|
size, and label string. The default boxtype is <TT>FL_DOWN_BOX</TT>.
|
|
<H4><A name=Fl_Output.~Fl_Output>virtual Fl_Output::~Fl_Output()</A></H4>
|
|
Destroys the widget and any value associated with it.
|
|
<H4><A name=Fl_Output.value>const char *Fl_Output::value() const
|
|
<BR> int Fl_Output::value(const char*)
|
|
<BR> int Fl_Output::value(const char*, int)</A></H4>
|
|
The first form returns the current value, which is a pointer to the
|
|
internal buffer and is valid only until the value is changed.
|
|
<P>The second two forms change the text and set the mark and the point
|
|
to the end of it. The string is copied to the internal buffer. Passing <TT>
|
|
NULL</TT> is the same as "". This returns non-zero if the new value is
|
|
different than the current one. You can use the second version to
|
|
directly set the length if you know it already or want to put nul's in
|
|
the text. </P>
|
|
<H4><A name=Fl_Output.size>int Fl_Output::size() const</A></H4>
|
|
Returns the number of characters in <TT>value()</TT>. This may be
|
|
greater than <TT>strlen(value())</TT> if there are nul characters in
|
|
it.
|
|
<H4><A name=Fl_Output.index>char Fl_Output::index(int) const</A></H4>
|
|
Same as <TT>value()[n]</TT>, but may be faster in plausible
|
|
implementations. No bounds checking is done.
|
|
<H4><A name=Fl_Output.textcolor>Fl_Color Fl_Output::textcolor() const
|
|
<BR> void Fl_Output::textcolor(Fl_Color)</A></H4>
|
|
Gets or sets the color of the text in the input field.
|
|
<H4><A name=Fl_Output.textfont>Fl_Font Fl_Output::textfont() const
|
|
<BR> void Fl_Output::textfont(Fl_Font)</A></H4>
|
|
Gets or sets the font of the text in the input field.
|
|
<H4><A name=Fl_Output.textsize>uchar Fl_Output::textsize() const
|
|
<BR> void Fl_Output::textsize(uchar)</A></H4>
|
|
Gets or sets the size of the text in the input field. </BODY></HTML>
