Now the window is ready to resize itself. As you may have noticed, all widgets have a RESIZE_XXX in their line. This lines controls how the widgets behave on resize. RESIZE_NONE means it doesn't do anything. Any other option let's one of the borders move with the changed width/height. So if a widget has RESIZE_RIGHT, and the window is made 5 pixels wider by the user, the right of the window will also be made 5 pixels wider. Now, what if you want to clamp a widget to the bottom? Give it the flag RESIZE_TB. This is RESIZE_TOP + RESIZE_BOTTOM. Now if the window gets 5 pixels bigger, both the top and bottom gets 5 bigger, so the whole widgets moves downwards without resizing, and appears to be clamped to the bottom. Nice aint it? You should know one more thing about this system. Most windows can't handle an increase of 1 pixel. So there is a step function, which let the windowsize only be changed by X pixels. You configure this after making the window, like this: w->resize.step_height = 10; Now the window will only change in height in steps of 10. You can also give a minimum width and height. The default value is the default height/width of the window itself. You can change this AFTER window - creation, with: w->resize.width or w->resize.height. That was all.. good luck, and enjoy :) -- TrueLight */ enum ResizeFlag { RESIZE_NONE = 0, ///< no resize required RESIZE_LEFT = 1, ///< left resize flag RESIZE_RIGHT = 2, ///< rigth resize flag RESIZE_TOP = 4, ///< top resize flag RESIZE_BOTTOM = 8, ///< bottom resize flag RESIZE_LR = RESIZE_LEFT | RESIZE_RIGHT, ///< combination of left and right resize flags RESIZE_RB = RESIZE_RIGHT | RESIZE_BOTTOM, ///< combination of right and bottom resize flags RESIZE_TB = RESIZE_TOP | RESIZE_BOTTOM, ///< combination of top and bottom resize flags RESIZE_LRB = RESIZE_LEFT | RESIZE_RIGHT | RESIZE_BOTTOM, ///< combination of left, right and bottom resize flags RESIZE_LRTB = RESIZE_LEFT | RESIZE_RIGHT | RESIZE_TOP | RESIZE_BOTTOM, ///< combination of all resize flags RESIZE_RTB = RESIZE_RIGHT | RESIZE_TOP | RESIZE_BOTTOM, ///< combination of right, top and bottom resize flag /* The following flags are used by the system to specify what is disabled, hidden, or clicked * They are used in the same place as the above RESIZE_x flags, Widget visual_flags. * These states are used in exceptions.
