刚刚学会了GTKMM的概念,并发现我很喜欢这个,而不仅仅是C ++,这在终端编程时非常无聊。当我决定创建一个会生成8 x 8按钮的代码时,我遇到了一个问题,就是如何将每个按钮设置到我想要的位置,因为我创建的代码只是水平地创建了64个按钮。有人能帮我一下吗?感谢
examplewindow.h(代码类属性和方法)
#ifndef GTKMM_EXAMPLEWINDOW_H
#define GTKMM_EXAMPLEWINDOW_H
#include <gtkmm.h>
class ExampleWindow : public Gtk::Window
{
public:
ExampleWindow();
virtual ~ExampleWindow();
private:
// Signal handlers:
void on_button_numbered(const Glib::ustring& data);
// Child widgets:
Gtk::Grid m_grid;
Gtk::Button button[8][8];
};
#endif /* GTKMM_EXAMPLEWINDOW_H */
examplewindow.cc(修改属性和方法的代码)
#include <iostream>
#include "examplewindow.h"
ExampleWindow::ExampleWindow()
{
set_title("Mr. Sandman");
set_border_width(12);
int i, j;
add(m_grid);
for (int i = 0; i < 8; i++)
{
for (int j = 0; j < 8; j++)
{
m_grid.add(button[i][j]);
}
}
for (int i = 0; i < 8; i++)
{
for (j = 0; j < 8; j++)
{
button[i][j].signal_clicked().connect(
sigc::bind<Glib::ustring>( sigc::mem_fun(*this,
&ExampleWindow::on_button_numbered), "button 1") );
}
}
m_grid.show_all();
}
ExampleWindow::~ExampleWindow()
{
}
void
ExampleWindow::on_button_numbered(const Glib::ustring& data)
{
std::cout << data << " was pressed" << std::endl;
}
main.cc(主要功能)
#include "examplewindow.h"
#include <gtkmm/application.h>
int main(int argc, char *argv[])
{
Glib::RefPtr<Gtk::Application> app = Gtk::Application::create(argc, argv, "org.gtkmm.example");
ExampleWindow window;
// Shows the window and returns when it is closed.
return app->run(window);
}
答案 0 :(得分:1)
而不是使用m_Grid.add()
尝试使用attach()
或attach_next_to()
所以你可以在你的循环中给出行/列位置,或者在按钮1下面添加按钮9,在按钮1的右边添加按钮2
