Can the newly added item be move to the top of a listbox and selected

[songdg]

I want to use GuiCtrl.Add(Items) method to add a new entry to a listbox, and move it to the top place.

Use GuiCtrl.Delete first, then add the entire list using GuiCtrl.Add() with the whole array that has the items in the order you want them (use Array.InsertAt(1) to add your new item at the top of the array). Then use GuiCtrl.Choose(1) to select the first item.

Another way using SendMessage:

Code: Select all

#Requires AutoHotkey v2.0

g := Gui()
g.AddText(, "Add a new item:")
myEdit := g.AddEdit("w150")
g.AddButton("yp", "Enter").OnEvent("Click", AddItemToListBox)
myListBox := g.AddListBox("xm r10 w200", ["apple", "orange", "banana"])
g.Show()

AddItemToListBox(*) {
    LB_INSERTSTRING := 0x0181
    index := 0 ; wParam is zero-indexed position to insert at
    SendMessage(LB_INSERTSTRING, index, StrPtr(myEdit.Text), myListBox)
    myListBox.Choose(1)
}

Thanks for the pretty much straight forward solution.

}

Probably a better solution , by the way what about delete an item, I know there is a LB_DELETESTRING := 0x0182 counterpart.

what about delete an item

GuiCtrl.Delete(Value) lets you specify the item to delete from a ListBox.
