This function sets the selected item from a dgs combobox.

Syntax

bool dgsDxComboBoxSetSelectedItem ( element comboBox, int itemIndex )

Required Arguments

  • comboBox: the dgs combobox you want to select an item from
  • itemIndex: the item you want to select (item 1 is the first item). If -1 is specified, then the combo box text is set to it's caption.

Returns

Returns true if the selected item has been changed successfully, false otherwise.

Example

This example creates a DGS window with a checked and an unchecked combo box and adds a command to toggle their visibility

DGS = exports.dgs
function drawGUI()
    dgsWindow = DGS:dgsDxCreateWindow(100,100,200,100,"ComboBox test area",false,false) -- create the container window
    combobox = DGS:dgsDxCreateComboBox(20,30,150,20,"Checked ComboBox",false,dgsWindow) -- note the parameter after header, it will create a ComboBox
    DGS:dgsDxComboBoxAddItem(combobox,"Selected") --Add items to combobox
    DGS:dgsDxComboBoxAddItem(combobox,"UnSelected")
    DGS:dgsDxComboBoxSetSelected(combobox,1)--set the first row which is the selected row Selected.
    DGS:dgsDxGUISetVisible(dgsWindow,false) -- set it invisible just in case
end

addCommandHandler("combobox",function()
    if not dgsWindow then -- if it hasn't been declared yet
        drawGUI() -- we draw the gui window
        DGS:dgsDxGUISetVisible(dgsWindow,true) -- we set it visible again. Strictly speaking it's not necessary, could have omitted both this and the upper dgsDxGUISetVisible, but this is needed if you want to cache a window without actually showing it
    else -- if we actually have run this function before and declared dgsWindow
        DGS:dgsDxGUISetVisible(dgsWindow, not guiGetVisible(dgsWindow)) -- we just toggle the visibility. If it was visible, not visible returns false and thus sets it's visibility false, effectivly hiding it	
    end
    showCursor(not isCursorShowing()) -- similar to above visibility
end)
