[Lazarus] TComboBox.DropDownCount has no effect.

[Vojtěch Čihák]

Hi,
 
DropDownCount works well in Qt but has no effect in GTk2 (and probably in Carbon too).
You can also see it in OI, tab "Restricted".

Hi All!

I have several apps that use combo boxes for (e.g.) Minutes.  For 
Minutes, the items range from 0 to 59.   The Object Inspector shows that 
the DropDownCount is 8, but no matter what I put in there, I get the 
entirety of the items.   For Minutes, the selection box spans the 
display from the top to the bottom, with the top part being blank and 
the bottom (from the position of the control itself) with 0, 1, ... 
until it hits the bottom of the screen.

To test this, create an application, put a TComboBox on the form, 
populate the Items with a set of items having more than 8 entries. Run 
the app and look at the number of items in the drop-down list. Change 
the DropDownCount to something like 3 and try again.  It always shows 
every item in the list no matter what is put in the Object Inspector.  
Additionally, in the FormCreate event, try setting 
ComboBox1.DropDownCount to something less than the number of Items.  The 
new value is totally ignored.

I am using Lazarus 1.4RC2 with no modifications on Linux Mint 17.

Am I doing something wrong?

Thanks,

Don Ziesig
