更改GtkButton的标签

Question

我希望能够在显示小部件后更改GtkButton的标签

char *ButtonStance == "Connect";
GtkWidget *EntryButton = gtk_button_new_with_label(ButtonStance);

gtk_box_pack_start(GTK_BOX(ButtonVbox), EntryButton, TRUE, TRUE, 0);

gtk_box_pack_start(GTK_BOX(TopVbox), ButtonVbox, TRUE, TRUE, 0);

gtk_widget_show_all(TopVbox);

ButtonStance == "Disconnect";

gtk_button_set_label(GTK_BUTTON(EntryButton), ButtonStance);

gtk_main();

有谁知道如何做到这一点？

ptomato是对的,你正在使用==你应该使用的地方=.
您的代码应如下所示:

char *ButtonStance = "Connect";
GtkWidget *EntryButton = gtk_button_new_with_label(ButtonStance);

gtk_box_pack_start(GTK_BOX(ButtonVbox), EntryButton, TRUE, TRUE, 0);

gtk_box_pack_start(GTK_BOX(TopVbox), ButtonVbox, TRUE, TRUE, 0);

gtk_widget_show_all(TopVbox);

ButtonStance = "Disconnect";

gtk_button_set_label(GTK_BUTTON(EntryButton), ButtonStance);

gtk_main();
