B4J Question combobox , how to set visible raws count programatically

[le_toubib]

Hi falks
How to show more Raws in a combobox dynamically?
thx

 

[Erel]

You can add items to the Items property:

cmb.Items.Add("New Item")

I was asking about how to "Show" more from the already added raws I.e : setmaxvisibleraw

 

[Erel]

Dim jo As JavaObject = ComboBox1
jo.RunMethod("setVisibleRowCount", Array(20))

You can get strange results from this as it seems to depend on the order you do things.

combo created in designer in both cases

1,
load layout
show form
add items
try to resize - size is wrong (seems to be just over 1 line high)
no resize - combo shows correct number of rows from designer.

2,
load layout
add items
show form
resize works as expected.

Maybe someone could confirm this

Maybe you should remove and add the items after you change this property.

Hi,

have tested (using latest version = JavaFX 8u40) "load layout, show form, add items, change visible rowcount" without issues.

See attached example.
