Hi all....
Currently in scheme, if we want to place any icon in toolbar we are using like this..::

(balloon (icon ".....") "hello..")

we are using this in "main-menu.scm" . In similar way as Icons, I want to replace them with QPushButtons.
I want to replace Icons with QPushButton widgets (push buttons)...I want to use same "balloon" function in scheme.
But It should provide pushbuttons in place of Icons.

Where I have to change the code...and...what function I should Use??

1. To introduce new scheme primitives you should look at Guile/Glue/ build-glue-basic.scm where you can define new widget creation functions like already done:

;; widgets
(widget-hmenu horizontal_menu (widget array_widget))
(widget-vmenu vertical_menu (widget array_widget))
(widget-tmenu tile_menu (widget array_widget int))
(widget-separator menu_separator (widget bool))
(widget-menu-group menu_group (widget string string))
(widget-pulldown-button pulldown_button (widget widget promise_widget))
(widget-pullright-button pullright_button (widget widget promise_widget))
(widget-menu-button menu_button (widget widget command string string bool))
(widget-balloon balloon_widget (widget widget widget))
(widget-empty empty_widget (widget))
(widget-text text_widget (widget string int bool string))
(widget-xpm xpm_widget (widget url))
(widget-box box_widget (widget scheme_tree string int bool bool))
(object->promise-widget as_promise_widget (promise_widget object))


2. define a new function pushbutton_widget and provide implementation like those in qt_*.cpp for the standard widget functions like
balloon_widget, text_widget, xpm_widget, etc...

3. reimplement the method qt_widget::as_qaction to returns a QWidgetAction which refers to you QPushButton.

HTH,
