Use this style to show + and - buttons to the left of parent items.
+ @style{wxTR_TWIST_BUTTONS}
+ Selects alternative style of @c +/@c - buttons and shows rotating
+ ("twisting") arrows instead. Currently this style is only implemented
+ under Microsoft Windows Vista and later Windows versions and is ignored
+ under the other platforms. Notice that under Vista this style results
+ in the same appearance as used by the tree control in Explorer and
+ other built-in programs and so using it may be preferable to the
+ default style.
@style{wxTR_NO_LINES}
Use this style to hide vertical level connectors.
@style{wxTR_FULL_ROW_HIGHLIGHT}
