problem with gtk_table_attach function using g++

[vineeta7]

hi

I am trying entry.c program given in tutorial (Linux Headquarters: GtkEntry - Single Line Text Entry Widget)
it is working properly using gcc.

But If i try it with g++.Then it is giving me error:

[vineeta@vineeta sample]$ gcc entry1.cpp -o entry1 `pkg-config --cflags --libs gtk+-2.0`
entry1.cpp: In function `int main(int, char**)':
entry1.cpp:56: invalid conversion from `int' to `GtkAttachOptions'
entry1.cpp:56: invalid conversion from `int' to `GtkAttachOptions'
entry1.cpp:57: invalid conversion from `int' to `GtkAttachOptions'
entry1.cpp:57: invalid conversion from `int' to `GtkAttachOptions'
entry1.cpp:58: invalid conversion from `int' to `GtkAttachOptions'
entry1.cpp:58: invalid conversion from `int' to `GtkAttachOptions'
entry1.cpp:59: invalid conversion from `int' to `GtkAttachOptions'
entry1.cpp:59: invalid conversion from `int' to `GtkAttachOptions'

how to resolve this error?

what is purpose of ORing in argument like this GTK_EXPAND | GTK_SHRINK | GTK_FILL??

For some reason it's not working , i don't know why exactly but you can tell your compiler that this value is (GtkAttachOptions)

so instead of doing like this :

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);

do like this

gtk_table_attach(GTK_TABLE(table), label1, 0, 1, 0, 1, (GtkAttachOptions)(GTK_EXPAND | GTK_SHRINK | GTK_FILL),(GtkAttachOptions) (GTK_EXPAND | GTK_SHRINK | GTK_FILL), 0, 0);

I didn't understand your second question !

Regards.
