<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.
|
|
|
|
<p><img src=text.gif>
|
|
|
|
<p>There is a single subclass, <a
|
|
href="#Fl_Multiline_Output">Fl_Multiline_Output</a>, which allows you to
|
|
display multiple lines of text.
|
|
|
|
<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.

<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.
|
|
|
|
<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.
