C语言 Gtk 3.0 文本视图可调整大小

Question

>我正在尝试创建一个文本区域，以便我可以创建一个文本编辑器，但是当文本到达窗口末尾时，它只会扩展并变大并且看起来很糟糕。

我已经在我的代码中尝试了多种方法来防止这种调整大小，但没有一个奏效。具有滚动功能的窗口会更容易吗？(我只是想让我的代码保持简单(

法典：

#include <gtk/gtk.h>
#include <stdio.h>
#include <stdlib.h>
static GtkTextBuffer *buffer;
void checkEndLine(GtkWidget *text, gpointer data){
//g_print(":%d ", gtk_text_buffer_get_char_count(GTK_TEXT_BUFFER(buffer)));
}
static void activate (GtkApplication *app, gpointer user_data){
GtkWidget *window, *grid, *calculate;
//Create Grid and Window
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_title(GTK_WINDOW(window), "Menu Test");
gtk_window_resize(GTK_WINDOW(window), 600, 600);
g_signal_connect(window, "destroy", G_CALLBACK(gtk_main_quit), NULL);
gtk_window_set_resizable(GTK_WINDOW(window), FALSE);
grid = gtk_grid_new();
gtk_container_add(GTK_CONTAINER(window), grid);
//Text Field
GtkWidget *largeEntry = gtk_text_view_new ();
GtkWidget *box = gtk_box_new(GTK_ORIENTATION_VERTICAL, 1);
gtk_widget_set_size_request(GTK_WIDGET(box), 100, 100);
gtk_widget_set_size_request(GTK_WIDGET(largeEntry), 100, 100);
gtk_widget_set_size_request(GTK_WIDGET(grid), 300, 300);
gtk_box_pack_start(GTK_BOX(box), largeEntry, 1, 1, 1);  
buffer = gtk_text_view_get_buffer (GTK_TEXT_VIEW (largeEntry));
gtk_text_buffer_set_text (buffer, "He", -1);

gtk_grid_attach(GTK_GRID(grid), box, 0, 1, 1, 1);
gtk_widget_set_hexpand_set(GTK_WIDGET(largeEntry), FALSE);
g_signal_connect(GTK_TEXT_BUFFER(buffer), "changed", G_CALLBACK(checkEndLine), NULL);
//Showing widgets 
gtk_widget_show_all(window);
gtk_main();
}
int main(int argc, char **argv){
GtkApplication *app;
int status;
app = gtk_application_new("com.calculate", G_APPLICATION_FLAGS_NONE);
g_signal_connect(app, "activate", G_CALLBACK (activate), NULL);
status = g_application_run (G_APPLICATION (app), argc, argv);
g_object_unref(app);
return status;
}

编译方式：

gcc note.c `pkg-config --cflags gtk+-3.0` -o out `pkg-config --libs gtk+-3.0`

通过设置换行模式，您可以阻止文本扩展窗口

gtk_text_view_set_wrap_mode(GTK_TEXT_VIEW(largeEntry), GTK_WRAP_WORD_CHAR);

但这只会阻止它水平扩展窗口。 要阻止它垂直扩展窗口，您必须将文本视图放在滚动窗口中。

#include <gtk/gtk.h>
#include <stdio.h>
#include <stdlib.h>
static GtkTextBuffer *buffer;
void checkEndLine(GtkWidget *text, gpointer data)
{
//g_print(":%d ", gtk_text_buffer_get_char_count(GTK_TEXT_BUFFER(buffer)));
}
static void activate(GtkApplication *app, gpointer user_data)
{
GtkWidget *window, *grid, *calculate;
//Create Grid and Window
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_title(GTK_WINDOW(window), "Menu Test");
gtk_window_resize(GTK_WINDOW(window), 600, 600);
g_signal_connect(window, "destroy", G_CALLBACK(gtk_main_quit), NULL);
gtk_window_set_resizable(GTK_WINDOW(window), FALSE);
grid = gtk_grid_new();
gtk_container_add(GTK_CONTAINER(window), grid);
//Text Field
GtkWidget *largeEntry = gtk_text_view_new();
GtkWidget *box = gtk_box_new(GTK_ORIENTATION_VERTICAL, 1);
GtkWidget *swindow = gtk_scrolled_window_new(NULL, NULL);
gtk_scrolled_window_set_policy(GTK_SCROLLED_WINDOW(swindow), GTK_POLICY_NEVER, GTK_POLICY_AUTOMATIC);
gtk_container_add(GTK_CONTAINER(swindow), largeEntry);
gtk_widget_set_size_request(GTK_WIDGET(swindow), 100, 100);
gtk_widget_set_size_request(GTK_WIDGET(largeEntry), 100, 100);
gtk_widget_set_size_request(GTK_WIDGET(grid), 300, 300);
gtk_box_pack_start(GTK_BOX(box), largeEntry, 1, 1, 1);
gtk_text_view_set_wrap_mode(GTK_TEXT_VIEW(largeEntry), GTK_WRAP_WORD_CHAR);

gtk_text_buffer_set_text(buffer, "He", -1);
gtk_grid_attach(GTK_GRID(grid), swindow, 0, 1, 1, 1);
gtk_widget_set_hexpand_set(GTK_WIDGET(largeEntry), FALSE);
