Make a tab
In making a tab, we use the following function.
ui_tab_create(x, y, width, height, contentHeight);
Where x and y are the tabs position is placed, the width is the overall width of the tab. If you use macros ui_default then it would be worth 480. The height is the height tabs. If you can use macros ui_default it will adjust the height of the text. The contentHeight is high of content tab by default, worth 320.
tabMenu = ui_tab_create (16, 32, 320, 32, 256)
The above line of code is used to create a tab with a certain position with handle size 32 and a size of 320 X 256 high content.
