Detailed Description

+The TQLabel widget provides a static information display +

+TQLabel is used for displaying information in the form of text or +image to the user. No user interaction functionality is +provided. The visual appearance of the label can be configured in +various ways, and it can be used for specifying a focus accelerator +key for another widget. +

A TQLabel can contain any of the following content types: +

+

When the content is changed using any of these functions, any +previous content is cleared. +

The look of a TQLabel can be tuned in several ways. All the settings +of TQFrame are available for specifying a widget frame. The +positioning of the content within the TQLabel widget area can be +tuned with setAlignment() and setIndent(). For example, this code +sets up a sunken panel with a two-line text in the bottom right +corner (both lines being flush with the right side of the label): +

    TQLabel *label = new TQLabel;
+    label->setFrameStyle( TQFrame::Panel | TQFrame::Sunken );
+    label->setText( "first line\nsecond line" );
+    label->setAlignment( AlignBottom | AlignRight );
+
+

A TQLabel is often used as a label for another, interactive +widget. For this use, TQLabel provides a handy mechanism for adding +an accelerator key (see TQAccel) that will set the keyboard focus to +the other widget (called the TQLabel's "buddy"). Example: +

     TQLineEdit* phoneEdit = new TQLineEdit( this, "phoneEdit" );
+     TQLabel* phoneLabel = new TQLabel( phoneEdit, "&Phone:", this, "phoneLabel" );
+
+

In this example, keyboard focus is transferred to the label's buddy +(the TQLineEdit) when the user presses Alt-P. You can also +use the setBuddy() function to accomplish the same. +

Member Function Documentation

+

TQLabel::TQLabel(TQWidget*buddy, constTQString&text, TQWidget*parent, constchar*name=0, WFlagsf=0)

+

Constructs a label with a text and a buddy. +

The text is set with setText(). The buddy is set with setBuddy(). +

The parent, name and f arguments are passed to the TQFrame +constructor. +

See also setText(), setBuddy(), setAlignment(), setFrameStyle() and setIndent(). +

TQLabel::TQLabel(TQWidget*parent, constchar*name=0, WFlagsf=0)

+

Constructs an empty label. +

The parent, name and f arguments are passed to the TQFrame +constructor. +

See also setAlignment(), setFrameStyle() and setIndent(). +

TQLabel::TQLabel(constTQString&text, TQWidget*parent, constchar*name=0, WFlagsf=0)

+

Constructs a label with a text. The text is set with setText(). +

The parent, name and f arguments are passed to the TQFrame +constructor. +

See also setText(), setAlignment(), setFrameStyle() and setIndent(). +

TQLabel::~TQLabel()

+

Destructs the label. +

intTQLabel::alignment()const

+

Returns the alignment setting. +

See also setAlignment(). +

boolTQLabel::autoResize()const

+

This function is obsolete. It is provided to keep old source working, and will probably be removed in a future version of TQt. We strongly advise against using it in new code.

+

Returns TRUE if auto-resizing is enabled, or FALSE if auto-resizing +is disabled. +

Auto-resizing is disabled by default. +

See also setAutoResize(). +

TQWidget*TQLabel::buddy()const

+

Returns the buddy of this label, or 0 if no buddy is currently set. +

See also setBuddy(). +

voidTQLabel::clear() [slot]

+

Clears any label contents. Equivalent with setText( "" ). +

voidTQLabel::drawContents(TQPainter*p) [virtualprotected]

+

Draws the label contents using the painter p. +

Reimplemented from TQFrame. +

voidTQLabel::drawContentsMask(TQPainter*p) [virtualprotected]

+

Draws the label contents mask using the painter p. +Used only in transparent mode. +

See also TQWidget::setAutoMask();. +

Reimplemented from TQFrame. +

voidTQLabel::fontChange(constTQFont&) [virtualprotected]

+

Reimplemented for internal reasons; the API is not affected. +

Reimplemented from TQWidget. +

boolTQLabel::hasScaledContents()const

+

Returns whether the label will scale its contents to fill all +available space. +

See also setScaledContents(). +

intTQLabel::heightForWidth(intw)const [virtual]

+

Reimplemented for internal reasons; the API is not affected. +

Reimplemented from TQWidget. +

intTQLabel::indent()const

+

Returns the indent of the label. +

See also setIndent(). +

TQSizeTQLabel::minimumSizeHint()const [virtual]

+

Reimplemented for internal reasons; the API is not affected. +

Reimplemented from TQWidget. +

TQMovie*TQLabel::movie()const

+

If the label contains a movie, returns a pointer to it. Otherwise, +returns 0. +

See also setMovie(). +

TQPixmap*TQLabel::pixmap()const

+

If the label contains a pixmap, returns a pointer to it. Otherwise, +returns 0. +

See also setPixmap(). +

voidTQLabel::resizeEvent(TQResizeEvent*e) [virtualprotected]

+

Reimplemented for internal reasons; the API is not affected. +

Reimplemented from TQWidget. +

voidTQLabel::setAlignment(intalignment) [virtual]

+

Sets the alignment of the label contents. +

The alignment must be a bitwise OR of TQt::AlignmentFlags +values. The WordBreak, ExpandTabs, SingleLine and ShowPrefix flags apply only if the label contains a plain text, and +are otherwise ignored. The DontClip flag is always ignored. +

If the label has a buddy, the ShowPrefix flag is forced to TRUE. +

The default alignment is AlignLeft | AlignVCenter | +ExpandTabs if the label doesn't have a buddy and +AlignLeft | AlignVCenter | ExpandTabs | ShowPrefix if +the label has a buddy. +

See also TQt::AlignmentFlags, alignment(), setBuddy() and setText(). +

Examples: + cursor/cursor.cpp + layout/layout.cpp + popup/popup.cpp + qmag/qmag.cpp + customlayout/main.cpp +

voidTQLabel::setAutoMask(boolb) [virtual]

+

Reimplemented for internal reasons; the API is not affected. +

Reimplemented from TQWidget. +

voidTQLabel::setAutoResize(boolenable) [virtual]

+

This function is obsolete. It is provided to keep old source working, and will probably be removed in a future version of TQt. We strongly advise against using it in new code.

+Enables auto-resizing if enable is TRUE, or disables it if enable is FALSE. +

When auto-resizing is enabled, the label will resize itself to fit +the contents whenever the contents change. The top left corner is +not moved. This is useful for TQLabel widgets that are not managed by +a TQLayout (e.g. top-level widgets). +

Auto-resizing is disabled by default. +

See also autoResize(), adjustSize() and sizeHint(). +

voidTQLabel::setBuddy(TQWidget*buddy) [virtual]

+

Sets the buddy of this label to buddy. +

When the user presses the accelerator key indicated by this label, +the keyboard focus is transferred to the label's buddy widget. +

The buddy mechanism is only available for TQLabels that contain a +plain text in which one letter is prefixed with '&'. It is this +letter that is set as the accelerator key. The letter is displayed +underlined, and the '&' is not displayed (i.e. the ShowPrefix +alignment flag is turned on; see setAlignment()). +

In a dialog, you might create two data entry widgets and a label for +each, and set up the geometry layout so each label is just to the +left of its data entry widget (its "buddy"), somewhat like this: +

    TQLineEdit *nameEd  = new TQLineEdit( this );
+    TQLabel    *nameLb  = new TQLabel( "&Name:", this );
+    nameLb->setBuddy( nameEd );
+    TQLineEdit *phoneEd = new TQLineEdit( this );
+    TQLabel    *phoneLb = new TQLabel( "&Phone:", this );
+    phoneLb->setBuddy( phoneEd );
+    // ( layout setup not shown )
+
+

With the code above, the focus jumps to the Name field when the user +presses Alt-N, and to the Phone field when the user presses Alt-P. +

To unset a previously set buddy, call this function with buddy +set to 0. +

See also buddy(), setText(), TQAccel and setAlignment(). +

Examples: + layout/layout.cpp +

voidTQLabel::setIndent(intindent)

+

Sets the indent of the label to indent pixels. +

The indent applies to the left edge if alignment() is AlignLeft, +to the right edge if alignment() is AlignRight, to the top edge +if alignment() is AlignTop, and to to the bottom edge if +alignment() is AlignBottom. +

If indent is negative, or if no indent has been set, the label +computes the effective indent as follows: If frameWidth() is 0, the +effective indent becomes 0. If frameWidth() is greater than 0, the +effective indent becomes half the width of the "x" character of the +widget's current font(). +

If indent is non-negative, the effective indent is indent +pixels. +

See also indent(), setAlignment(), frameWidth() and font(). +

Examples: + movies/main.cpp +

voidTQLabel::setMovie(constTQMovie&movie) [virtualslot]

+

Sets the label contents to movie. Any previous content is cleared. +

The buddy accelerator, if any, is disabled. +

The label resizes itself if auto-resizing is enabled. +

See also movie() and setBuddy(). +

voidTQLabel::setNum(doublenum) [virtualslot]

+

Sets the label contents to a plain text containing the printed value +of num. Does nothing if this is equal to the current contents of +the label. Any previous content is cleared. +

The buddy accelerator, if any, is disabled. +

The label resizes itself if auto-resizing is enabled. +

See also setText(), TQString::setNum() and setBuddy(). +

voidTQLabel::setNum(intnum) [virtualslot]

+

Sets the label contents to a plain text containing the printed value +of num. Does nothing if this is equal to the current contents of +the label. Any previous content is cleared. +

The buddy accelerator, if any, is disabled. +

The label resizes itself if auto-resizing is enabled. +

See also setText(), TQString::setNum() and setBuddy(). +

voidTQLabel::setPixmap(constTQPixmap&pixmap) [virtualslot]

+

Sets the label contents to pixmap. Any previous content is cleared. +

The buddy accelerator, if any, is disabled. +

The label resizes itself if auto-resizing is enabled. +

See also pixmap() and setBuddy(). +

voidTQLabel::setScaledContents(boolenable)

+

When called with enable == TRUE, and the label shows a pixmap, +it will scale the pixmap to fill available space. +

See also hasScaledContents(). +

voidTQLabel::setText(constTQString&text) [virtualslot]

+

Sets the label contents to text, or does nothing if text is +equal to the current contents of the label. Any previous content is +cleared. +

text will be interpreted either as a plain text or as a rich +text, depending on the text format setting; see setTextFormat(). The +default setting is AutoText, i.e. TQLabel will try to auto-detect +the format of text. +

If text is interpreted as a plain text, and a buddy has been set, +the buddy accelerator key is updated from the new text. +

The label resizes itself if auto-resizing is enabled. +

Note that Qlabel is well suited to display small rich text documents +only. For large documents, use TQTextView instead. It will flicker +less on resize and can also provide a scrollbar if necessary. +

See also text(), setTextFormat(), setBuddy() and setAlignment(). +

Examples: + cursor/cursor.cpp + layout/layout.cpp + popup/popup.cpp + qmag/qmag.cpp + customlayout/main.cpp +

voidTQLabel::setTextFormat(TQt::TextFormatformat)

+

Sets the text format to format. See the TQt::TextFormat enum for +an explanation of the possible options. +

The default format is AutoText. +

See also textFormat() and setText(). +

TQSizeTQLabel::sizeHint()const [virtual]

+

Reimplemented for internal reasons; the API is not affected. +

Examples: + layout/layout.cpp +

Reimplemented from TQWidget. +

TQSizePolicyTQLabel::sizePolicy()const [virtual]

+

Reimplemented for internal reasons; the API is not affected. +

Reimplemented from TQWidget. +

TQStringTQLabel::text()const

+

Returns the label text. If the content is a plain or a rich text, +this is the string that was passed to setText(). Otherwise, it is an +empty/null string. +

See also setText(), setNum() and clear(). +

TQt::TextFormatTQLabel::textFormat()const

+

Returns the current text format. +
