Gtk::Button::Button | ( | ) |
Create an empty button.
With an empty button, you can Gtk::Button::add() a widget such as a Gtk::Pixmap or Gtk::Box.
If you just wish to add a Gtk::Label, you may want to use the Gtk::Button(const Glib::ustring& label) ctor directly instead.
Gtk::Button::Button | ( | const Glib::ustring & | label, | |
bool | mnemonic = false | |||
) | [explicit] |
Simple Push Button with label.
Create a button with the given label inside. You won't be able to add a widget in this button since it already has a Gtk::Label in it
Gtk::Button::Button | ( | const StockID& | stock_id | ) | [explicit] |
Creates a new Button containing the image and text from a stock item.
Stock ids have identifiers like Gtk::Stock::OK and Gtk::Stock::APPLY.
stock_id | The stock item. |
void Gtk::Button::clicked | ( | ) |
void Gtk::Button::enter | ( | ) |
void Gtk::Button::get_alignment | ( | float & | xalign, | |
float & | yalign | |||
) |
Gets the alignment of the child in the button.
xalign | Return location for horizontal alignment. | |
yalign | Return location for vertical alignment. |
bool Gtk::Button::get_focus_on_click | ( | ) | const |
Returns whether the button grabs focus when it is clicked with the mouse.
See set_focus_on_click().
true
if the button grabs focus when it is clicked with the mouse.const Widget* Gtk::Button::get_image | ( | ) | const |
Gets the widget that is currenty set as the image of button .
This may have been explicitly set by set_image() or specified as a stock item to the constructor.

Widget* Gtk::Button::get_image | ( | ) |
Gets the widget that is currenty set as the image of button .
This may have been explicitly set by set_image() or specified as a stock item to the constructor.

Glib::ustring Gtk::Button::get_label | ( | ) | const |
Fetches the text from the label of the button, as set by set_label().
If the label text has not been set the return value will be 0
. This will be the case if you create an empty button with new() to use as a container.
ReliefStyle Gtk::Button::get_relief | ( | ) | const |
bool Gtk::Button::get_use_stock | ( | ) | const |
Returns whether the button label is a stock item.
true
if the button label is used to select a stock item instead of being used directly as the label text. bool Gtk::Button::get_use_underline | ( | ) | const |
Returns whether an embedded underline in the button label indicates a mnemonic.
See set_use_underline().
true
if an embedded underline in the button label indicates the mnemonic accelerator keys. const GtkButton* Gtk::Button::gobj | ( | ) | const [inline] |
Provides access to the underlying C GtkObject.
Reimplemented from Gtk::Bin.
Reimplemented in Gtk::CheckButton, Gtk::ColorButton, Gtk::FontButton, Gtk::OptionMenu, Gtk::RadioButton, and Gtk::ToggleButton.

void Gtk::Button::set_alignment | ( | float | xalign, | |
float | yalign | |||
) |
Sets the alignment of the child.
This property has no effect unless the child is a Gtk::Misc or a Gtk::Aligment.
xalign | The horizontal position of the child, 0.0 is left aligned, 1.0 is right aligned. | |
yalign | The vertical position of the child, 0.0 is top aligned, 1.0 is bottom aligned. |
void Gtk::Button::set_focus_on_click | ( | bool | focus_on_click = true |
) |
Sets whether the button will grab focus when it is clicked with the mouse.
Making mouse clicks not grab focus is useful in places like toolbars where you don't want the keyboard focus removed from the main area of the application.
focus_on_click | Whether the button grabs focus when clicked with the mouse. |
void Gtk::Button::set_image | ( | Widget& | image | ) |
Set the image of button to the given widget.
Note that it depends on the gtk-button-images setting whether the image will be displayed or not, you don't have to call Gtk::Widget::show() on image yourself.
image | A widget to set as the image for the button. |
void Gtk::Button::set_label | ( | const Glib::ustring & | label | ) |
Sets the text of the label of the button to str .
This text is also used to select the stock item if set_use_stock() is used.
This will also clear any previously set labels.
label | A string. |
void Gtk::Button::set_relief | ( | ReliefStyle | newstyle | ) |
void Gtk::Button::set_use_stock | ( | bool | use_stock = true |
) |
If true, the label set on the button is used as a stock id to select the stock item for the button.
use_stock | true if the button should use a stock item. |
void Gtk::Button::set_use_underline | ( | bool | use_underline = true |
) |
If true, an underline in the text of the button label indicates the next character should be used for the mnemonic accelerator key.
use_underline | true if underlines in the text indicate mnemonics. |
