Hi Experts,

I am creating gtkentry widget. I set default text in it. On running, the program I get the expected text but it comes by default selected. I do not want the text appearing in gtkentry as selected and I want to set the cursor to some 'x' position in the default text. How can I do that?

Thanks beforehand.

Kind Regards

Hello -Durgesh O Mishra,

Please try gtk_editable_set_position ().

Hi,

set_position works but when I try to unselect the by default selected text by select_region of gtk_editable it simply does nothing.

Kind Regards

Hello.

Can you post a minimalistic but complete (compilable) application that demonstrates this problem? I've done some GtkEntry patching cca. a week from now and I don't remember seeing anything unusual in it's code that would cause this behavior.

Here is the code.

Even after setting the region from 1 to 3. It still keeps the whole text selected by default.

gint destroyapp (GtkWidget *widget, gpointer gdata)
{
g_print ("Quitting...\n");
gtk_main_quit();
return (FALSE);
}

int main (int argc, char *argv[])
{
/*-- Declare the GTK Widgets used in the program --*/
GtkWidget *window;
GtkWidget *table;
GtkWidget *label1;
GtkWidget *label2;
GtkWidget *entry1;
GtkWidget *entry2;

/*-- Initialize GTK --*/
gtk_init (&argc, &argv);

/*-- Create the new window --*/
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

/*-- Create the entry widgets --*/
entry1 = gtk_entry_new();
entry2 = gtk_entry_new();

/*-- Set entry2 to be non-editable --*/
gtk_entry_set_editable(GTK_ENTRY(entry2), FALSE);

/*-- Create the text --*/
gtk_entry_set_text(GTK_ENTRY(entry1), "Some text...");
gtk_entry_append_text(GTK_ENTRY(entry1), "Some more text appended");
gtk_entry_set_text(GTK_ENTRY(entry2), "Some text...");
gtk_entry_append_text(GTK_ENTRY(entry2), "Some more text appended");

/* deselect the gtk_entry */
gtk_editable_select_region(GTK_EDITABLE(entry1),1,3);

/*--Create the labels --*/
label1 = gtk_label_new("Editable text entry widget:");
label2 = gtk_label_new("Non-editable text entry widget:");

/*-- Create the 2x2 table --*/
table = gtk_table_new(2, 2, FALSE);

/*-- Connect the window to the destroyapp function --*/
gtk_signal_connect(GTK_OBJECT(window), "delete_event", GTK_SIGNAL_FUNC(destroyapp), NULL);

/*-- Add the items to the table --*/
gtk_table_attach(GTK_TABLE(table), label1, 0, 1, 0, 1, GTK_EXPAND | GTK_SHRINK | GTK_FILL, GTK_EXPAND | GTK_SHRINK | GTK_FILL, 0, 0);
gtk_table_attach(GTK_TABLE(table), label2, 0, 1, 1, 2, GTK_EXPAND | GTK_SHRINK | GTK_FILL, GTK_EXPAND | GTK_SHRINK | GTK_FILL, 0, 0);
gtk_table_attach(GTK_TABLE(table), entry1, 1, 2, 0, 1, GTK_EXPAND | GTK_SHRINK | GTK_FILL, GTK_EXPAND | GTK_SHRINK | GTK_FILL, 0, 0);
gtk_table_attach(GTK_TABLE(table), entry2, 1, 2, 1, 2, GTK_EXPAND | GTK_SHRINK | GTK_FILL, GTK_EXPAND | GTK_SHRINK | GTK_FILL, 0, 0);

/*-- Add the table to the window --*/
gtk_container_add(GTK_CONTAINER(window), table);

/*-- Set window border to zero so that text area takes up the whole window --*/
gtk_container_border_width (GTK_CONTAINER (window), 5);

/*-- Set the window to be 640 x 480 pixels --*/
gtk_window_set_default_size (GTK_WINDOW(window), 500, 100);

/*-- Set the window title --*/
gtk_window_set_title(GTK_WINDOW (window), "GtkEntry");

/*-- Display the widgets --*/
gtk_widget_show(table);
gtk_widget_show(entry1);
gtk_widget_show(entry2);
gtk_widget_show(label1);
gtk_widget_show(label2);
gtk_widget_show(window);

/*-- Start the GTK event loop --*/
gtk_main();

/*-- Return 0 if exit is successful --*/
return 0;
}

Hi.

You're having problems because GtkEntry and it's buffer are not properly initialized yet when you call gtk_editable_select_region(). Move this line of code after the last gtk_widget_show() call and thing will work as expected.
