[Solved]Dialog ctrl ComboBox show matching autocomplete list

[JulianR]

Hi!

My users want a ComboBox that shows a list of matching items as the user types in the name of item.

Is there a way to force ComboBox dialog control to display the list of items programatically? I can't seem to find any such method or property with xray when inspecting one.

I can make a Function, that will generate necessary String Item List, but that alone without auto displaying the narrowed down list makes little sense.

I tried myself to look if I could open an OO combobox dropdown from OOBasic but failed to find a way.
It can be opened with the keyboard rather than the mouse by pressing Alt + the down arrow.
You could try a combination of textbox + listbox instead of a combobox.

Use a multi-line list box (drop down property = No) and tell your users that you can type into a focussed list box.

Thanks guys, I'll give those options a try.

It might be possible to get the combo to open by simulating a mouse click with Windows api calls (like mouse_event) - though I couldn't manage that.

Another option would be to make something combo-like using a second dialog as your dropdown - see attached example. As you're on Windows, for speed, I've used code from VBHelper to change the window style of the 'dropdown' dialog to remove the titlebar.

An OO dialog without titlebar can be created by modifying this code:

Code: Select all

dlg.getcontrol("ComboBox1").AccessibleContext.doAccessibleAction(0)

Thank you JeJe, it works flawlessly.
