Gtk基础学习总结(二)

一、信号、事件

void g_signal_connect(instance,char* signalName,callback,gpointerobject);

//instance:gtk控件

int btnOnClick(GtkWidget *widget,int data);

例:  g_signal_connect(window,"destroy",gtk_main_quit,NULL);

 

//添加Clicked事件

GtkButton *btn1=gtk_button_new();

gtk_button_set_label(btn1,"按钮");

gtk_container_add(window,btn1);

g_signal_connect(btn1,"clicked",btn1OnClicked,NULL);

gtk_widget_show(btn1);

 

二、Gtk控件

//复选框CheckButton

//GtkCheckButton *cb1=gtk_check_button_new_with_label("嘿嘿");

cbAgree=gtk_check_button_new();

gtk_button_set_label(cbAgree,"同意以上协议.");

gtk_box_pack_start(box,cbAgree,FALSE,FALSE,0);

gtk_widget_show(cbAgree);

g_signal_connect(cbAgree,"clicked",cbAgreeOnClick,NULL);

 

//单选框RadioButton

GtkRadioButton *radio1=gtk_radio_button_new_with_label(NULL,"男");

GtkRadioButton *radio2=gtk_radio_button_new_with_label_from_widget(radio1,"女"); // 和radio1同一组

gtk_box_pack_start(box,radio1,FALSE,FALSE,0);

gtk_box_pack_start(box,radio2,FALSE,FALSE,0);

gtk_widget_show(radio1);

gtk_widget_show(radio2);

 

//文本框entry

entryName=gtk_entry_new();

gtk_entry_set_max_length(entryName,5); //设置输入的最大长度

gtk_entry_set_visibility(entryName,FALSE); //设置为密码框风格

gtk_box_pack_start(box,entryName,FALSE,FALSE,0);

gtk_widget_show(entryName);

 

//标签label

labelResult=gtk_label_new("");

gtk_box_pack_start(box,labelResult,FALSE,FALSE,0);

gtk_widget_show(labelResult);

 

//组合框ComboBoxText

cmbGril=gtk_combo_box_text_new();

gtk_box_pack_start(box,cmbGril,FALSE,FALSE,0);

gtk_combo_box_text_append(cmbGril,"wm","吴淼");

gtk_combo_box_text_append(cmbGril,"wd","吴东");

gtk_combo_box_text_append (cmbGril,"wxq","吴晓青");

gtk_combo_box_set_active_id(cmbGril,"wd");

//changed事件

g_signal_connect(cmbGril,"changed",cmbGrilOnChanged,NULL);

gtk_widget_show(cmbGril);

 

//GtkImage，支持JPG、GIF、PNG等，不支持BMP GtkImage

*img1=gtk_image_new();

//gtk_image_set_from_file(img1,"D:\\00_13.jpg");

gtk_image_set_from_stock(img1,GTK_STOCK_ADD,GTK_ICON_SIZE_DIALOG);

gtk_box_pack_start(box,img1,FALSE,FALSE,0); gtk_widget_show(img1);

 

 //带图片按钮

GtkImage *img=gtk_image_new();

gtk_image_set_from_stock(img,GTK_STOCK_APPLY,GTK_ICON_SIZE_BUTTON);

gtk_widget_show(img);

GtkButton *btn=gtk_button_new_with_label("确定");

gtk_button_set_image(btn,img);

gtk_container_add(window,btn );

gtk_widget_show(btn);
