On my screen there are a pushbutton and a tabsrtip control which contain two tabs.
initial,the tabstrip is visible,and the button with icon_collapse icon.
then,i click the button ,and the tabstrip must be invisible,and the button's icon will change to icon_expand.
if i use screen-name conditions to set the tab invisible,but the tabstrip has a shadow on the screen.the color of the space obtained by the tabstrip is different with other space's color.
How can i set the color same with other if i want to hide the tabstrip.
ths very much.
