This function creates a combobox GUI element, which you can compare to a gridlist with a dropdown feature.

[[{{{image}}}|link=|]] Note: The height of a combobox must be enough to fit the drop down menu, else the drop down won't appear. See guiComboBoxAdjustHeight to give your combobox the correct height.

Syntax

Example GUI ComboBox.
element guiCreateComboBox ( float x, float y, float width, float height, string caption, [ bool relative = false, gui-element parent = nil ] )

OOP Syntax Help! I don't understand this!

Method: GuiComboBox(...)


Required Arguments

  • x: A float of the 2D x position of the GUI combobox on a player's screen. This is affected by the relative argument.
  • y: A float of the 2D y position of the GUI combobox on a player's screen. This is affected by the relative argument.
  • width: A float of the width of the GUI combobox. This is affected by the relative argument.
  • height: A float of the height of the GUI combobox. This is affected by the relative argument. Note: height must be enough to fit the drop down menu, else the drop down won't appear.
  • caption: A string for what the title of your combobox will be. This will be shown if no item is selected.

Optional Arguments

NOTE: When using optional arguments, you might need to supply all arguments before the one you wish to use. For more information on optional arguments, see optional arguments.

  • relative: This is whether sizes and positioning are relative. If this is true, then all x,y,width,height floats must be between 0 and 1, representing sizes relative to the parent.
  • parent: This is the parent that the GUI combobox is attached to. If the relative argument is true, sizes and positioning will be made relative to this parent. If the relative argument is false, positioning will be the number of offset pixels from the parent's origin. If no parent is passed, the parent will become the screen - causing positioning and sizing according to screen positioning.

Returns

Returns an element of the created combobox if it was successfully created, false otherwise.

Example

This example creates a combo box in the center of the screen with all server vehicles on it. 

addEventHandler ("onClientResourceStart",resourceRoot,function()
	local screenWidth, screenHeight = guiGetScreenSize()
	local windowWidth, windowHeight = 200,100
	local left = screenWidth/2 - windowWidth/2
	local top = screenHeight/2 - windowHeight/2
	local vehiclesComboBox = guiCreateComboBox ( left, top, windowWidth,windowHeight, "Vehicle Names", false ) -- We create a combo box.
	for index, vehicle in ipairs ( getElementsByType ( "vehicle" ) ) do -- We loop through all vehicles.
		guiComboBoxAddItem ( vehiclesComboBox, getVehicleName ( vehicle ) ) -- We add the vehicle name to our combo box.
	end
end)
