TCheckComboBox multiselect
« on: November 30, 2015, 08:35:07 pm »

Hi everybody, just a question about the TCheckComboBox component

When working with the TcheckComboBox component and trying to do a multiselect, each time we select an option in the TCheckComboBox, the component closes and then we need to open it again to select another one.

Anybody knows if there is any way to mantain the TCheckComboBox opened until all the desired options were selected?

Thanks in advance.

I cannot see any way to do it (single nor cross platform).
IIRC I implemented both TComboBoxEx and TCheckComboBox myself few years ago.

Reason is that there's practically no control of opened combo box. All you get are repiant events ( DrawItem(); ) on hovering and mouse click always closes combo. I don't know any way to change it.
