DESCRIPTION

Tk::ColoredButton is an extension of the Tk::Canvas::GradientColor widget. It is an easy way to simulate a button widget with gradient background color.

STANDARD OPTIONS

The following the Tk::Button manpage options are supported :

-activebackground -activeforeground -anchor -background -bitmap -borderwidth -command -compound -cursor -disabledforeground -font -foreground -height -highlightbackground -highlightcolor -highlightthickness -image -justify -padx -pady -relief -repeatdelay -repeatinterval -state -takefocus -text -textvariable -width -wraplength

WIDGET-SPECIFIC OPTIONS

There are many options which allow you to configure your button as you want.

Name: activeGradient
Class: ActiveGradient
Switch: -activegradient => hash reference
Specifies gradient background color to use when the mouse cursor is positioned over the button. Please read the options of the set_gradientcolor method of the Tk::Canvas::GradientColor manpage to understand the options. 

  -activegradient => {
    -start_color  => '#BFD4E8',
    -end_color    => '#FFFFFF',
    -type         => 'mirror_vertical',
    -start        => 50,
    -number_color => 10
  },

Default : { -start_color => '#FFFFFF', -end_color => '#B2B2B2' }

Name: autofit
Class: Autofit
Switch: -autofit => 1 or 0
Enables automatic adjustment (width and height) of the button depending on the displayed content (text, image, bitmap, ...). 

  -autofit => 1,

Default : 0

Name: gradient
Class: Gradient
Switch: -gradient
Specifies gradient background color on the button. Please read the options of the set_gradientcolor method of set_gradientcolor in the Tk::Canvas::GradientColor manpage to understand the options. 

  -gradient => {
    -start_color  => '#FFFFFF',
    -end_color    => '#BFD4E8',
    -type         => 'mirror_vertical',
    -start        => 50,
    -number_color => 10
  },

Default : { -start_color => '#B2B2B2', -end_color => '#FFFFFF' }

-height or -width
Specifies a desired window height/width that the button widget should request from its geometry manager. The value may be specified in any of the forms described in the COORDINATES in the Tk::Canvas manpage section below.

You can also use the autofit option if you want to have an automatic adjustment for your button.

Default : -height => 20, -width => 80,

Name: imageDisabled
Class: ImageDisabled
Switch: -imagedisabled => $image_photo
Specifies an image to display in the button when it is disabled. ( See the Tk::Photo manpage or the Tk::Image manpage for details of image creation.). 
  -imagedisabled => $image_photo,

Default : undef

Name: tooltip
Class: Tooltip
Switch: -tooltip => $tooltip or [$tooltip, $iniwait?]
Creates and attaches help balloons (using the Tk::Balloon manpage). Then, when the mouse pauses over the button, a help balloon is popped up.

$iniwait Specifies the amount of time to wait without activity before popping up a help balloon. Specified in milliseconds. Defaults to 350 milliseconds. This applies to both the popped up balloon and the status bar message.

  -tooltip => 'my button message',         
  -tooltip => ['my button message', 200],

Default : undef

WIDGET-SPECIFIC METHODS

You can use invoke method like in the Tk::Button manpage.

delete_tooltip

$button_bgc->delete_tooltip
Delete the help balloon created with tooltip option. 
  $button_bgc->delete_tooltip;

flash

$button_bgc->flash(?$interval) in ms
Flash the button. This is accomplished by change foreground color of the button several times, alternating between active and normal colors. At the end of the flash the button is left in the same normal/active state as when the command was invoked. This command is ignored if the button's state is disabled.

$interval is the time in milliseconds between each alternative.

If $interval is not specified, the button will alternate between active and normal colors every 300 milliseconds.

If $interval is zero, any current flash operation will be cancel.

If $interval is non-zero, the button will alternate every $interval milliseconds until it is explicitly cancelled via $interval to zero or using cancel method to id returned.

  my $id = $button_bgc->flash(1000);
  $button_bgc->flash(0); # Cancel the flash

redraw_button

$button_bgc->redraw_button
Re-creates the button. Tk::ColoredButton supports the configure and cget methods described in the the Tk::options manpage manpage. If you use configure method to change a widget specific option, the modification will not be display. You have to update your widget by redraw it using this method. 
  $button_bgc->redraw_button;
