使用VS2010 编写的GTK程序不用修改能否移植到linux下

我没有用VS2010编写过GTK程序，但是，在 Linux 下我用 Anjuta 编写GTK程序时发现，其方便性与 VS2010 编写程序相当，建议你不妨试用，把源代码复制粘贴过来，或许能解决你的移植需求。

使用 gtk 截图后不需要保存文件，直接通过内存中的数据进行显示。

首先安装 gtk :

然后编写应用程序：

使用以下命令进行编译:

void enter_callback( GtkWidget widget,

GtkWidget entry )

{

const gchar entry_text;

entry_text = gtk_entry_get_text (GTK_ENTRY (entry));

printf("Entry contents: %s\n", entry_text);

}

void entry_toggle_editable( GtkWidget checkbutton,

GtkWidget entry )

{

gtk_editable_set_editable (GTK_EDITABLE (entry),

GTK_TOGGLE_BUTTON (checkbutton)->active);

}

void entry_toggle_visibility( GtkWidget checkbutton,

GtkWidget entry )

{

gtk_entry_set_visibility (GTK_ENTRY (entry),

GTK_TOGGLE_BUTTON (checkbutton)->active);

}

/ 我们常见的回调函数 /

void callback( GtkWidget widget,

gpointer data )

{

g_print ("Hello again - %s was pressed\n", (char ) data);

}

int main( int argc, char argv[])

{

GtkWidget window;

GtkWidget ok;

GtkWidget close;

GtkWidget text_view;

GtkTextBuffer buffer;

GtkWidget vbox;

GtkWidget hbox;

GtkWidget halign;

GtkWidget valign;

gtk_init(&argc, &argv);

//=============Build a window===========//

window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);

gtk_window_set_default_size(GTK_WINDOW(window), 350, 280);

gtk_window_set_title(GTK_WINDOW(window), "Labyrinth");

gtk_container_set_border_width(GTK_CONTAINER(window), 10);

g_signal_connect_swapped(G_OBJECT(window), "destroy",

G_CALLBACK(gtk_main_quit), G_OBJECT(window));

//=============Adjust layout============//

vbox = gtk_vbox_new(FALSE, 5);

valign = gtk_alignment_new(0, 1, 0, 0);

gtk_container_add(GTK_CONTAINER(vbox), valign);

gtk_container_add(GTK_CONTAINER(window), vbox);

hbox = gtk_hbox_new(TRUE, 3);

//=============Build tow button========//

ok = gtk_button_new_with_label("OK");

gtk_widget_set_size_request(ok, 70, 30);

gtk_container_add(GTK_CONTAINER(hbox), ok);

close = gtk_button_new_with_label("Close");

gtk_container_add(GTK_CONTAINER(hbox), close);

halign = gtk_alignment_new(1, 0, 0, 0);

close = gtk_button_new_from_stock (GTK_STOCK_CLOSE);

gtk_container_add(GTK_CONTAINER(halign), hbox);

gtk_box_pack_start(GTK_BOX(vbox), halign, FALSE, FALSE, 0);

g_signal_connect_swapped (G_OBJECT (close), "clicked",

G_CALLBACK (gtk_widget_destroy),

window);

GTK_WIDGET_SET_FLAGS (close, GTK_CAN_DEFAULT);

gtk_widget_grab_default (close);

gtk_widget_show (close);

//=============Build a TestView==========//

text_view=gtk_text_view_new();/创建文本框构件/

gtk_widget_set_size_request(text_view,200,200);

gtk_container_add(GTK_CONTAINER(window),vbox);

gtk_box_pack_start(GTK_BOX(vbox),text_view,FALSE,FALSE,0);

buffer=gtk_text_view_get_buffer(GTK_TEXT_VIEW(text_view));

gtk_widget_show(text_view);

//=============================

GtkWidget entry;

gint tmp_pos;

entry = gtk_entry_new ();

gtk_entry_set_max_length (GTK_ENTRY (entry), 50);

g_signal_connect (G_OBJECT (entry), "OK",

G_CALLBACK (enter_callback), entry);

gtk_entry_set_text (GTK_ENTRY (entry), "hello");

tmp_pos = GTK_ENTRY (entry)->text_length;

gtk_editable_insert_text (GTK_EDITABLE (entry), " world", -1, &tmp_pos);

gtk_editable_select_region (GTK_EDITABLE (entry),

0, GTK_ENTRY (entry)->text_length);

// tmp_pos = GTK_ENTRY (entry)->text_length;

// gtk_editable_insert_text (GTK_EDITABLE (entry), " hello ", -1, &tmp_pos);

// gtk_editable_select_region (GTK_EDITABLE (entry),

// 0, GTK_ENTRY (entry)->text_length);

gtk_box_pack_start (GTK_BOX (vbox), entry, TRUE, TRUE, 0);

gtk_widget_show (entry);

gtk_widget_show_all(window);

gtk_main();

return 0;

}
