To gtk team,
I´m developing an app with drag and drop operation between 2 treeviews and I
have had some problems with dnd mechanism.
I do a G_VALUE_ARRAY to hold the following selected datas. I was fulfill in
signal ON_DRAG_GET.
Tabela is my gvaluearray and datas I wanna hold are, number of columns, name of
columns, type of columns and datas of lines like below:
Number of columns(N), colname1, colname2, colname3,colname, ...
,colnameN,typeofcol1,typeofcol2, ... ,typeofcolN, data1, data2, data3, ... ,
dataN
When a print values int to ON_DRAG_GET signal I can see all values there. This
structure is ready to copy to selectiondata.
I use the following command to put this gvaluearray into selectiondata.
gtk_selection_data_set(sdata,
gdk_atom_intern ("gvaluearray_wetest", FALSE),
4, /* Tell GTK how to pack the data (bytes) */
(void*)tabela,//(void*)&tabela, /* The actual pointer that we just
made */
sizeof(tabela));
Into ON_DRAG_RECEIVED signal when I copy selection data with memcpy I have a
surprise. Gtk selection has the same structure but data is empty. And only one
data is copied and it is wrong. It is a genum.
What I´m doing wrong.
Thank you.
