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 { + RESIZE_NONE = 0, + + RESIZE_LEFT = 1, + RESIZE_RIGHT = 2, + RESIZE_TOP = 4, + RESIZE_BOTTOM = 8, + + RESIZE_LR = RESIZE_LEFT | RESIZE_RIGHT, + RESIZE_RB = RESIZE_RIGHT | RESIZE_BOTTOM, + RESIZE_TB = RESIZE_TOP | RESIZE_BOTTOM, + RESIZE_LRB = RESIZE_LEFT | RESIZE_RIGHT | RESIZE_BOTTOM, + RESIZE_LRTB = RESIZE_LEFT | RESIZE_RIGHT | RESIZE_TOP | RESIZE_BOTTOM, + RESIZE_RTB = RESIZE_RIGHT | RESIZE_TOP | RESIZE_BOTTOM, +}; + typedef struct Widget { byte type; + byte resize_flag; byte color; uint16 left, right, top, bottom; uint16 unkA; @@ -41,6 +85,12 @@ union WindowEvent { struct { byte event; + Point size; + Point diff; + } sizing; + + struct { + byte event; byte *str; } edittext; @@ -163,6 +213,7 @@ enum { WDF_RESTORE_DPARAM = 8, /* when drawing widgets, restore the dparam so all widgets recieve the same set of them */ WDF_UNCLICK_BUTTONS=16, /* Unclick buttons when the window event times out */ WDF_STICKY_BUTTON =32, /* Set window to sticky mode; they are not closed unless closed with 'X' (widget 2) */ + WDF_RESIZABLE =64, /* A window can be resized */ }; /* can be used as x or y coordinates to cause a specific placement */ @@ -192,22 +243,32 @@ typedef struct { uint16 count, cap, pos; } Scrollbar; +typedef struct { + uint width; /* Minimum width and height */ + uint height; + + uint step_width; /* In how big steps the width and height go */ + uint step_height; +} ResizeInfo; + struct Window { uint16 flags4; WindowClass window_class; WindowNumber window_number; - int left,top; - int width,height; + int left, top; + int width, height; Scrollbar hscroll, vscroll, vscroll2; + ResizeInfo resize; byte caption_color; uint32 click_state, disabled_state, hidden_state; WindowProc *wndproc; ViewPort *viewport; - const Widget *widget; + const Widget *original_widget; + Widget *widget; //const WindowDesc *desc; uint32 desc_flags; @@ -347,6 +408,7 @@ enum WindowEvents { WE_CREATE = 19, WE_MOUSEOVER = 20, WE_ON_EDIT_TEXT_CANCEL = 21, + WE_RESIZE = 22, }; @@ -377,7 +439,8 @@ enum WindowWidgetTypes { WWT_HSCROLLBAR = 11, WWT_STICKYBOX = 12, WWT_SCROLL2BAR = 13, /* 2nd vertical scrollbar*/ - WWT_LAST = 14, /* Last Item. use WIDGETS_END to fill up padding!! */ + WWT_RESIZEBOX = 14, + WWT_LAST = 15, /* Last Item. use WIDGETS_END to fill up padding!! */ WWT_MASK = 31, @@ -386,7 +449,7 @@ enum WindowWidgetTypes { WWT_NODISTXTBTN = WWT_TEXTBTN | WWB_NODISBUTTON, }; -#define WIDGETS_END WWT_LAST, 0, 0, 0, 0, 0, 0, STR_NULL +#define WIDGETS_END WWT_LAST, RESIZE_NONE, 0, 0, 0, 0, 0, 0, STR_NULL enum WindowFlags { WF_TIMEOUT_SHL = 0, @@ -398,7 +461,7 @@ enum WindowFlags { WF_HSCROLL = 1 << 7, WF_SIZING = 1 << 8, WF_STICKY = 1 << 9, - + WF_DISABLE_VP_SCROLL = 1 << 10, WF_WHITE_BORDER_ONE = 1 << 11, @@ -427,6 +490,10 @@ Window *StartWindowDrag(Window *w); Window *StartWindowSizing(Window *w); Window *FindWindowFromPt(int x, int y); +bool IsWindowOfPrototype(Window *w, const Widget *widget); +void AssignWidgetToWindow(Window *w, const Widget *widget); +/* Use this function to save the current widget to be the global default */ +void MakeWindowWidgetDefault(Window *w); Window *AllocateWindow( int x, int y, |
