Gtk +：如何在表格中左侧对齐标签

Question

我目前正在使用gtk库，尝试使用C创建一个简单的窗口应用程序，但是我在表格中对齐标签时遇到了一些困难。

更具体地说，这是我到目前为止所写的内容：

#include<gtk/gtk.h>


static void dest(GtkWidget*, gpointer);

int main(int argc, char *argv[]) {

    GtkWidget *window;
    GtkWidget *table;
    GtkWidget *label1, *folderChooser1;
    GtkWidget *label2, *folderChooser2;

    gtk_init(&argc,&argv);


    /*************************************
     * setting the first row in table
     *************************************/
    label1=gtk_label_new("Browse For a Folder To Backup: ");
    //gtk_misc_set_alignment(GTK_MISC(label1), 0, .5);              // neither this
    //gtk_label_set_justify(GTK_LABEL(label1, GTK_JUSTIFY_LEFT);    // nor this aligns the label to the left.
    folderChooser1=gtk_file_chooser_button_new("Browse For Folder...", GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER);
    gtk_file_chooser_set_current_folder(GTK_FILE_CHOOSER (folderChooser1), g_get_home_dir());


    /*************************************
     * setting the second row
     *************************************/
    label2=gtk_label_new("Choose Backup Path: ");
    //gtk_misc_set_alignment(GTK_MISC(label2), 0, .5);              // neither this
    //gtk_label_set_justify(GTK_LABEL(label2, GTK_JUSTIFY_LEFT);    // nor this aligns the label to the left.
    folderChooser2=gtk_file_chooser_button_new("Browse For Folder...", GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER);
    gtk_file_chooser_set_current_folder(GTK_FILE_CHOOSER (folderChooser2), g_get_home_dir());


    /***************************************
     * setting table
     ***************************************/
    table=gtk_table_new(2,2,TRUE);
    gtk_table_attach(GTK_TABLE(table), label1, 0, 1, 0, 1, GTK_SHRINK, GTK_SHRINK, 15, 0);
    gtk_table_attach(GTK_TABLE(table), label2, 0, 1, 1, 2, GTK_SHRINK, GTK_SHRINK, 15, 0);
    gtk_table_attach_defaults(GTK_TABLE(table), folderChooser1, 1, 2, 0, 1);
    gtk_table_attach_defaults(GTK_TABLE(table), folderChooser2, 1, 2, 1, 2);


    /********************************
     * setting window 
     ********************************/
    window=gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_title(GTK_WINDOW(window), "Backup");
    gtk_window_set_resizable(GTK_WINDOW(window), FALSE);
    gtk_container_set_border_width(GTK_CONTAINER(window), 10);

    g_signal_connect(G_OBJECT(window), "destroy", G_CALLBACK(dest), NULL);
    gtk_container_add(GTK_CONTAINER (window), table);   

    gtk_widget_show_all(window);

    gtk_main();
    return 0;
}


static void dest(GtkWidget *window, gpointer data) {
    gtk_main_quit();
}

上面的代码将产生这个：

正如您所看到的，标签位于中心位置，我想要将其标记为左侧。 没有一条注释掉的线路对我有用 有没有办法在表格单元格内对齐标签？

只要我还使用gtk_misc_set_alignment附加标签，

gtk_table_attach_defaults对我有用：

完整的参考代码：

#include<gtk/gtk.h>


static void dest(GtkWidget*, gpointer);

int main(int argc, char *argv[]) {

    GtkWidget *window;
    GtkWidget *table;
    GtkWidget *label1, *folderChooser1;
    GtkWidget *label2, *folderChooser2;

    gtk_init(&argc,&argv);


    /*************************************
     * setting the first row in table
     *************************************/
    label1=gtk_label_new("Browse For a Folder To Backup: ");
    gtk_misc_set_alignment(GTK_MISC(label1), 0, .5);              // neither this
    //gtk_label_set_justify(GTK_LABEL(label1, GTK_JUSTIFY_LEFT);    // nor this aligns the label to the left.
    folderChooser1=gtk_file_chooser_button_new("Browse For Folder...", GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER);
    gtk_file_chooser_set_current_folder(GTK_FILE_CHOOSER (folderChooser1), g_get_home_dir());


    /*************************************
     * setting the second row
     *************************************/
    label2=gtk_label_new("Choose Backup Path: ");
    gtk_misc_set_alignment(GTK_MISC(label2), 0, .5);              // neither this
    //gtk_label_set_justify(GTK_LABEL(label2, GTK_JUSTIFY_LEFT);    // nor this aligns the label to the left.
    folderChooser2=gtk_file_chooser_button_new("Browse For Folder...", GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER);
    gtk_file_chooser_set_current_folder(GTK_FILE_CHOOSER (folderChooser2), g_get_home_dir());


    /***************************************
     * setting table
     ***************************************/

    table=gtk_table_new(2,2,TRUE);
    //gtk_table_attach(GTK_TABLE(table), label1, 0, 1, 0, 1, GTK_SHRINK, GTK_SHRINK, 15, 0);
    //gtk_table_attach(GTK_TABLE(table), label2, 0, 1, 1, 2, GTK_SHRINK, GTK_SHRINK, 15, 0);
    gtk_table_attach_defaults(GTK_TABLE(table), label1, 0, 1, 0, 1);
    gtk_table_attach_defaults(GTK_TABLE(table), label2, 0, 1, 1, 2);
    gtk_table_attach_defaults(GTK_TABLE(table), folderChooser1, 1, 2, 0, 1);
    gtk_table_attach_defaults(GTK_TABLE(table), folderChooser2, 1, 2, 1, 2);

    /********************************
     * setting window
     ********************************/
    window=gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_title(GTK_WINDOW(window), "Backup");
    gtk_window_set_resizable(GTK_WINDOW(window), FALSE);
    gtk_container_set_border_width(GTK_CONTAINER(window), 10);

    g_signal_connect(G_OBJECT(window), "destroy", G_CALLBACK(dest), NULL);
    gtk_container_add(GTK_CONTAINER (window), table);

    gtk_widget_show_all(window);

    gtk_main();
    return 0;
}


static void dest(GtkWidget *window, gpointer data) {
    gtk_main_quit();
}
