我仍然不熟悉使用widget工具包,但我认为这应该可行。我从developer.gnome.org复制了这段代码,并将自己的对象(button2)添加到Buttons类中,但只有原始的m_button显示在窗口中。 buttons.h的内容:
#ifndef GTKMM_EXAMPLE_BUTTONS_H
#define GTKMM_EXAMPLE_BUTTONS_H
#include <gtkmm/window.h>
#include <gtkmm/button.h>
class Buttons : public Gtk::Window
{
public:
Buttons()
{
m_button.add_pixlabel("info.xpm", "hi");
button2.add_pixlabel("info.xpm", "hello");
set_title("Pixmap'd buttons!");
set_border_width(10);
m_button.signal_clicked().connect( sigc::mem_fun(*this,
&Buttons::on_button_clicked) );
add(button2);
add(m_button);
show_all_children();
}
virtual ~Buttons()
{
}
protected:
//Signal handlers:
void on_button_clicked()
{
}
//Child widgets:
Gtk::Button button2;
Gtk::Button m_button;
};
#endif //GTKMM_EXAMPLE_BUTTONS_H
main.cpp的内容:
#include "buttons.h"
#include <gtkmm/application.h>
int main(int argc, char *argv[])
{
Glib::RefPtr<Gtk::Application> app =
Gtk::Application::create(argc, argv,
"org.gtkmm.examples.base");
Buttons buttons;
return app->run(buttons);
}
答案 0 :(得分:4)
我目前也在学习Gtkmm,所以这可能不是最好的答案,但我认为这样做的正确方法是添加Gtk :: Box对象,然后将Gtk :: Buttons添加到Gtk: :箱
我就是这样做的。此外,我已将您的标题gtkmm_example_buttons.h拆分为gtkmm_example_buttons.hpp和gtkmm_example_buttons.cpp我也将按钮名称m_button更改为button1以匹配button2名称,因为它具有一致性。
//gtkmm_example_buttons.hpp
#pragma once //used instead of the ifdef
#include <gtkmm/window.h>
#include <gtkmm/button.h>
#include <gtkmm/box.h>
class Buttons : public Gtk::Window
{
public:
Buttons();
virtual ~Buttons();
protected:
void on_button_clicked();
Gtk::Button button1, button2;
Gtk::Box box1;
};
此外,我已经删除了信号处理,因为它们只会使代码更复杂。稍后您将了解更多信息。
//gtkmm_example_buttons.cpp
#include "gtkmm_example_buttons.hpp"
#include <gtkmm/window.h>
#include <gtkmm/button.h>
#include <gtkmm/box.h>
Buttons::Buttons()
{
button1.add_pixlabel("info.xpm", "hi");
button2.add_pixlabel("info.xpm", "hello");
set_title("Pixmap'd buttons!");
set_border_width(10);
add(box1);
box1.pack_start(button1);
box1.pack_start(button2);
show_all_children();
}
Buttons::~Buttons()
{
}
void Buttons::on_button_clicked()
{
}
主要:
//main.cpp
#include "gtkmm_example_buttons.hpp"
#include <gtkmm.h>
int main (int argc, char *argv[])
{
auto app = Gtk::Application::create(argc, argv, "org.gtkmm.test");
//Shows the window and returns when it is closed.
Buttons buttons;
return app->run(buttons);
}
