Combo box problems

Searched the forum for this one but no luck. Any idea how I can achieve the following?

  1. Set height of combo box so I can fit longer sentences?
  2. Change colour of box?
  3. Change size of text and font?

tried changing txt font with this code but it didn’t work…

myComboBox.[color=#000084]setStyleProperty[/color]("[color=#0000ff]textFont[/color]","[color=#0000ff]Courier New[/color]");

Any idea how I can sort this out?
