Ked som kedysi robil property grid, tak som potreboval vlozit do
TreeView tlacidlo a odchytavat click. Teda nieco podobne ako chcete vy.
Spravil som si vlastny renderer. Prikladam ho v prilohe. Urcite ho
nebudete chciet pouzit 1:1, ale ako priklad hadam postaci

Mam treeview. V nem zobrazuji nejake zbozi z liststore. V jednom
sloupci zobrazuji pixbuf. Po jednom kliknuti na nejaky cell z toho
sloupce bych potreboval, aby se zavolala moje funkce f().
Konkretne: tukanim na obrazek pluska se zvysi pocet polozek ve skladu.
Zkousel jsem to pres signaly row-activated, cursor-changed, ale vzdycky
musim kliknout 2x:(
Rad uvitam primo ukazky kodu ci jine reseni.
Kdyz tak tu hodim i kod pro predstavu.
