Macro Combobox prevent editing but allow selection?

#1

Using python macro to create a dialog with a combobox. Would it be possible to block a combobox for typing, but stay active to choose an item in the dropdown list?
I tried this

cbb_test.setEditable(False)

and that

add_widget(‘combobox’, ‘ComboBox’, MARGIN, MARGIN + LBL_HEIGHT + SEP, WIDTH - MARGIN * 2, CBB_HEIGHT, {‘StringItemList’: choices, ‘Text’: default, ‘Dropdown’: True, ‘ReadOnly’: True})

but both cases block the combobox preventing the selection of an item

Don’t you use a list box for any reason?

In this case of only one listbox in the dialog, I can use the listbox, but if there were several widgets in the dialog, the combobox would take up less space. So I wanted to know if it’s possible to have a read-only combobox, but selectable like in other frameworks.

Same example using listbox:

    ctx = XSCRIPTCONTEXT.getComponentContext()
    sm = ctx.ServiceManager

    if with_context:
        instance = sm.createInstanceWithContext(name, ctx)
    else:
        instance = sm.createInstance(name)
    return instance


def msg(message, title='LibreOffice', buttons=MSG_BUTTONS.BUTTONS_OK, type_msg='INFOBOX'):

    parent = toolkit.getDesktopWindow()
    mb = toolkit.createMessageBox(parent, type_msg, buttons, title, str(message)+'\n\n')
    return mb.execute()


def dialog_choice(message, title='', choices=[], default='', x=None, y=None):
    WIDTH = 500
    MARGIN = 8
    BUTTON_WIDTH = 100
    BUTTON_HEIGHT = 26

    LABEL_HEIGHT = 16

    listbox = dialog.getControl('listbox')

There is a difference in terminology between Microsoft Office Forms and LibreOfiice Forms (Dialogs). You need a Listbox with model’s Dropdown property set to True (see also colleague’s @KamilLanda answer).

It really was a terminology problem, I corrected the listbox code to Dropdown = True , and it worked as I needed it to.

Thank you all for your help

corrected code:

Sorry that example is in Basic, I’m very busy today and probably also tomorrow.
It is example how to set the same listbox like in Dialogs in Basic IDE - there isn’t typing of text, only selecting from Listbox.

Sub pridatListBox 'set the same Listbox like in Dialogs in Basic IDE
	dim oModel
	oModel=createUNOservice("stardiv.Toolkit.UnoControlListBoxModel")
	o=createUNOservice("stardiv.Toolkit.UnoListBoxControl")
	o.setModel(oModel)
	o.Model.StringItemList=array("aaa","bb", "ccc", "d", "e", "ff")
	o.Model.DropDown=true
	o.DropDownLineCount=5
	goHlavniDialog.addControl("xxx", o)
	o=goHlavniDialog.getControl("xxx")
	o.setPosSize(10, 100, 400, 26, 15)
End Sub
