CBS_DROPDOWN select all empty text

[AntoninoP]

Hello,
I did this simple test:

Code: Select all

#include <fivewin.ch>

proc main()
   LOCAL oWnd, oCombo, cValue// := Space(100)
   DEFINE WINDOW oWnd
   @ 1,1 COMBOBOX oCombo VAR cValue SIZE 200,200 STYLE CBS_DROPDOWN
   //oCombo:oGet:SetSel() //this does nothing
   ACTIVATE WINDOW oWnd

My problem is that when the application starts, the text inside the combobox is all selected:


I see there is no way to avoid the TGet creation on CBS_DROPDOWN, personally I would prefer the TEdit control

hi,

My problem is that when the application starts, the text inside the combobox is all selected:

i see ... empty

i'm still a FiveWin Newbie so i not know Syntax.
under Xbase++ i "set" most pre-select 1st Element from DropDown List into EDIT Part of ComboBox

Code: Select all

   oCombo:setData( {1} )

hi,

My problem is that when the application starts, the text inside the combobox is all selected:

i see ... empty

my problem is the blue rectangle...

with

Code: Select all

ACTIVATE WINDOW oWnd ON INIT (oCombo:oGet:SetSel())

I obtain a semi-acceptable result

[Jimmy]

my problem is the blue rectangle...

sorry i don't understand what your Problem with Frame is
do you want "no Frame" or "small Frame with long Text" or other Color of Frame ...

with

Code: Select all

ACTIVATE WINDOW oWnd ON INIT (oCombo:oGet:SetSel())

I obtain a semi-acceptable result

ok so it is not empty any more a 1st ist select only, or
