[solved] Add Remove new key Combos after onCombination is Called.

[blackholeearth]

how can i add new combinations after calling OnCombination(mydictionary).

if i call onCombination. then whatever i add on dictionary donest have any effect. its ignored.

static Dictionary<Combination, Action> comboDictionary= new Dictionary<Combination, Action>();

form1_load()
{
           comboDictionary.Add(Combination.FromString("Ctrl+4") , CookPotatoStew );
           Hook.GlobalEvents().OnCombination(keycombo_act_list );
            
          //this doesnt work.
           comboDictionary.Add(Combination.FromString("Ctrl+5") , CookChicken );

}

void CookPotatoStew() { MessageBox.Show("Here is your PotatoStew .."); }
void CookChicken()    { MessageBox.Show("Here is your Chicken ..");    }
void CookApplePie()   { MessageBox.Show("Here is your ApplePie..");    }

okay i checked the code. found a way to Push new KeyCombinations.

here, how to use;

public static CombinationData comboDictionary_Updater;

static Dictionary<Combination, Action> comboDictionary= new Dictionary<Combination, Action>();

form1_load()
{
           comboDictionary.Add(Combination.FromString("Ctrl+4") , CookPotatoStew );
           Hook.GlobalEvents().OnCombination_v2(keycombo_act_list );
            
          //add Keys
           comboDictionary.Add(Combination.FromString("Ctrl+5") , CookChicken );
           comboDictionary.Add(Combination.FromString("Ctrl+6") , CookApplePie );

          //UpdateKeys - call this after add remove Combo is done.
            comboDictionary_Updater?.UpdateCombinations(comboDictionary);
}

void CookPotatoStew() { MessageBox.Show("Here is your PotatoStew .."); }
void CookChicken()    { MessageBox.Show("Here is your Chicken ..");    }
void CookApplePie()   { MessageBox.Show("Here is your ApplePie..");    }
