-
- Area class is a super class for every other MUI class
- except windows and applications. It holds information
- about an objects current position, size and weight
- and manages frames, fonts and backgrounds.
-
- Additionally, area class handles the user input. By
- setting an objects MUIA_InputMode, you can make it
- behave like a button or like a toggle gadget. That's
- why MUI doesn't offer an extra button class. A button
- is simply a text object with a raised frame and a relverify
- input mode. Since especially group class is a subclass
- of area, you can create rather complex buttons consisting
- of many other display elements.

- Area.mui/MUIA_ApplicationObject
-
- NAME
- MUIA_ApplicationObject -- (V4) [..G], Object *
-
- FUNCTION
- You can obtain a pointer to the application object
- that some gadget belongs to by using this attribute.
- Useful mainly within callback hooks if you do not want
- to deal with global variables.
-
- SEE ALSO
- MUIA_WindowObject
- Area.mui/MUIA_Background
-
- NAME
- MUIA_Background -- (V4) [IS.], LONG
-
- FUNCTION
- Adjust the background for an object.
-
- Every MUI object has its own background setting.
- The background is displayed "behind" the actual
- object contents, e.g. behind a the text of a
- text object or behind the image of an image object.
-
- This attribute takes the same values as MUIA_Image_Spec,
- please refer to autodocs of image class for a complete
- description.
-
- An object without a specific background setting will
- inherit the pattern from its parent group. The default
- background for a window and many other background
- patterns are adjustable with the preferences program.
-
- Only a few MUII_xxxxxxx tags make sense as background.
- Important are:
-
- MUII_ButtonBack:
- You have to set this when you create a button gadget.
- Thus, your button will be displayed in the users
- preferred style.
-
- MUII_TextBack:
- Set this when you create a text object with a TextFrame,
- e.g. some kind of status line. Do *not* use MUII_TextBack
- for simple text without frame (e.g. gadget labels).
-
- MUII_BACKGROUND
- MUII_SHADOW
- MUII_SHINE
- MUII_FILL
- MUII_SHADOWBACK
- MUII_SHADOWFILL
- MUII_SHADOWSHINE
- MUII_FILLBACK
- MUII_FILLSHINE
- MUII_SHINEBACK
- MUII_SHINEBACK2:
- One of MUI's predefined pattern. These are not
- configurable by the user and will always look the
- same.
-
- Note: It is *important* that you test your programs with
- a fancy pattern configuration. With the default
- setting you won't notice any errors in your backgrounds.
- Area.mui/MUIA_BottomEdge
-
- NAME
- MUIA_BottomEdge -- (V4) [..G], LONG
-
- FUNCTION
- You can use this to read the current position and
- dimension of an object, if you e.g. need it to pop
- up some requester below.
-
- Of course, this attribute is only valid when the
- parent window of the object is currently open.
-

- MUIA_RightEdge, MUIA_LeftEdge
- Area.mui/MUIA_ControlChar
-
- NAME
- MUIA_ControlChar -- (V4) [I..], char
-
- FUNCTION
- Pressing the control char will have the same effect
- as pressing return if the object was active.
-
- This can be used to create old style key shortcuts.
-
- Note: Using an uppercase control char will force
- the user to press shift.
-

- Area.mui/MUIA_Disabled
-
- NAME
- MUIA_Disabled -- (V4) [ISG], BOOL
-
- FUNCTION
- Disable or enable a gadget. Setting this attribute
- causes a gadget to become disabled, it gets a ghost
- pattern and doesn't respond to user input any longer.
-
- Disabled gadgets cannot be activated with the TAB key.
-
- Using MUIA_Disable on a group of objects will disable
- all objects within that group.
-
- EXAMPLE
- /* we have a radio button gadget with three */
- /* entries, the third should enable a string gadget */
- /* with additional parameters */
-
- DoMethod(radio, MUIM_Notify, MUIA_Radio_Active, 0,
- string, 3, MUIM_Set, MUIA_Disabled, TRUE);
-
- DoMethod(radio, MUIM_Notify, MUIA_Radio_Active, 1,
- string, 3, MUIM_Set, MUIA_Disabled, TRUE);
-
- DoMethod(radio, MUIM_Notify, MUIA_Radio_Active, 2,
- string, 3, MUIM_Set, MUIA_Disabled, FALSE);
- Area.mui/MUIA_ExportID
-
- NAME
- MUIA_ExportID -- (V4) [ISG], LONG
-
- FUNCTION
- Objects with a non NULL MUIA_ExportID export their
- contents during MUIM_Application_Save and import
- them during MUIM_Application_Load.
-
- You have to use different ExportIDs for your objects!
-
- SEE ALSO

- Area.mui/MUIA_FixHeight
-
- NAME
- MUIA_FixHeight -- (V4) [I..], LONG

- MUIV_Font_Fixed
- MUIV_Font_Title
- MUIV_Font_Big
-
- FUNCTION
- Every MUI object can have its own font, just set it with
- this tag. Objects without an explicit font setting will
- inherit it from their parent group.
-
- You normally won't need to open a font yourself, just
- use one of the predefined values to get a font from
- the users preferences.
-
- EXAMPLE
- /* since the text contains tabs, */
- /* use the fixed width font for displaying */
-

- MUIV_Frame_Gauge
- MUIV_Frame_Group
- MUIV_Frame_PopUp
- MUIV_Frame_Virtual
- MUIV_Frame_Slider
- MUIV_Frame_Count
-
- FUNCTION
- Define a frame for the current object. Since area class
- is a superclass for all elements in a window, you can
- assign frames to every object you wish.
-
- You don't adjust the style of your frame directly,
- instead you only specify a type:
-
- MUIV_Frame_Button
- for standard buttons with text in it.
-
- MUIV_Frame_ImageButton
- for small buttons with images, e.g. the arrows
- of a scrollbar.
-
- MUIV_Frame_Text
- for a text field, e.g. a status line display.
-
- MUIV_Frame_String
- for a string gadget.
-
- MUIV_Frame_ReadList
- for a read only list.
-
- MUIV_Frame_InputList
- for a list that handles input (has a cursor).
-
- MUIV_Frame_Prop
- for proportional gadgets.
-
- MUIV_Frame_Group
- for groups.
-
- How the frame is going to look is adjustable via the
- preferences program.
-
- Four spacing values belong to each frame that tell
- MUI how many pixels should be left free between the
- frame and its contents. These spacing values are also
- user adjustable as long as you don't override them
- with one of the MUIA_InnerXXXX tags.
-
- Note: The first object in a window (MUIA_Window_RootObject)
- may *not* have a frame. If you need this you will have
- to create a dummy group with just one child.
-

- strobj = StringObject,
- MUIA_Frame, MUIV_Frame_String,
- End;

- Area.mui/MUIA_FramePhantomHoriz
-
- NAME
- MUIA_FramePhantomHoriz -- (V4) [I..], BOOL
-
- FUNCTION
- Setting this to TRUE causes the specified frame to be
- a horizontal phantom frame. The frame will not appear
- but its vertical components (frame height, inner
- top and inner bottom spacing) will be used to calculate
- positions and dimensions (horizontal components are
- treated as 0).
-
- This is extremely useful for a correct labeling of objects.
- You would e.g. label a string gadget by using a text object
- with a phantom string frame. Thus, the label text will
- be always on the same vertical position as the string
- gadget text, no matter what spacing values the user
- configured.
-
- SEE ALSO
- Label() macros in "mui.h".
- Area.mui/MUIA_FrameTitle
-
- NAME
- MUIA_FrameTitle -- (V4) [I..], STRPTR
-
- FUNCTION
- This tag identifies a text string that will be displayed
- centered in the top line of a frame. This can become
- handy if you want to name groups of objects.
-
- You may not use MUIA_FrameTitle without defining
- a MUIA_Frame.
-
- EXAMPLE
- VGroup,
- MUIA_Frame , MUIV_Frame_Group,
- MUIA_FrameTitle, "Spacing",
- ...
-
- SEE ALSO
- MUIA_Frame
- Area.mui/MUIA_Height

- MUIA_Height -- (V4) [..G], LONG
-
- FUNCTION
- You can use this to read the current position and

- Area.mui/MUIA_HorizWeight
-
- NAME
- MUIA_HorizWeight -- (V4) [I..], LONG
-
- FUNCTION
- Adjust the horizontal weight of an object. Usually
- you can simply use MUIA_Weight instead of this tag
- but in some two-dimensional groups it may become
- handy to have different horizontal and vertical
- weights.
-
- SEE ALSO
- MUIA_Weight
- Area.mui/MUIA_InnerBottom
-
- NAME
- MUIA_InnerBottom -- (V4) [I..], LONG
-

- SPECIAL INPUTS
- MUIV_InputMode_None
- MUIV_InputMode_RelVerify
- MUIV_InputMode_Immediate
- MUIV_InputMode_Toggle
-
- FUNCTION
- Adjust the input mode for an object.
-
- MUI has no distinct button class. Instead you can make
- every object (even groups) behave like a button by
- setting an input mode for them. Several input modes
- area available:
-
- MUIV_InputMode_None:
- No input, this is not a gadget.
-
- MUIV_InputMode_RelVerify:
- For buttons and similar stuff.
-
- MUIV_InputMode_Immediate:
- Used e.g. in a radio button object.
-
- MUIV_InputMode_ToggleSelect:
- For things like checkmark gadgets.
-
- The input mode setting determines how a user action
- will trigger the attributes MUIA_Selected, MUIA_Pressed
- and MUIA_Timer. See their documentation for details.
-
- EXAMPLE
- /* A traditional button, just a text object with */
- /* a button frame and a relverify input mode: */
-
- okbutton = TextObject,
- MUIA_Frame , MUIV_Frame_Button,
- MUIA_InputMode , MUIV_InputMode_RelVerify,

- NAME
- MUIA_LeftEdge -- (V4) [..G], LONG
-
- FUNCTION
- You can use this to read the current position and
- dimension of an object, if you e.g. need it to pop
- up some requester below.
-
- Of course, this attribute is only valid when the
- parent window of the object is currently open.

- Area.mui/MUIA_Pressed
-
- NAME
- MUIA_Pressed -- (V4) [..G], BOOL
-
- FUNCTION
- Learn if a button is pressed (or released).
- The MUIA_Pressed attribute of a gadget is triggered
- by some user action, depending on the input mode:
-
- MUIV_InputMode_RelVerify:
- - set when lmb is pressed.
- - cleared when lmb is released and the mouse
- is still over the gadget (otherwise it will
- be cleared too, but without triggering a
- notification event).
-
- MUIV_InputMode_Immediate:
- - undefined, use MUIA_Selected for this.
-
- MUIV_InputMode_Toggle:
- - undefined, use MUIA_Selected for this.
-
- Waiting for MUIA_Pressed getting FALSE is the usual
- way to react on button gadgets.
-
- EXAMPLE
- DoMethod(btcancel,MUIM_Notify,MUIA_Pressed,FALSE,
- app,2,MUIM_Application_ReturnID,ID_CANCEL);

- Area.mui/MUIA_RightEdge
-
- NAME
- MUIA_RightEdge -- (V4) [..G], LONG
-
- FUNCTION
- You can use this to read the current position and
- dimension of an object, if you e.g. need it to pop
- up some requester below.
-
- Of course, this attribute is only valid when the

- Area.mui/MUIA_Selected
-
- NAME
- MUIA_Selected -- (V4) [ISG], BOOL
-
- FUNCTION
- Get and set the selected state of a gadget.
- This attribute can be triggered by the user
- clicking on the gadget (or using the keyboard),
- depending on the input mode:
-
- MUIV_InputMode_RelVerify:
- - set when lmb is pressed.
- - cleared when lmb is released.
- - cleared when the gadget is selected and the
- mouse leaves the gadget box.
- - set when the mouse reenters the gadget box.
-
- MUIV_InputMode_Immediate:
- - set when lmb is pressed.
-
- MUIV_InputMode_Toggle:
- - toggled when lmb is pressed.
-
- Of course you may set this attribute yourself, e.g.
- to adjust the state of a checkmark gadget.
-
- A selected gadget will display its border reverse
- and get the configured MUII_SelectedBack background.
- This can be avoided using the MUIA_ShowSelState tag.
-
- SEE ALSO
- MUIA_Pressed, MUIA_Timer, MUIA_ShowSelState, MUIA_InputMode
- Area.mui/MUIA_ShowMe
-
- NAME
- MUIA_ShowMe -- (V4) [ISG], BOOL
-
- FUNCTION
- Objects with this attribute set are not displayed. You can
- set MUIA_ShowMe at any time, causing objects to appear and
- to disappear immediately. A new layout is calculated whenever
- some objects are shown or hidden. When necessary, MUI will
- resize the parent window to make place for the new objects.
-
- NOTE
- Currently, MUI does a complete window refresh after
- showing/hiding objects. This behaviour might get improved
- in the future.
- Area.mui/MUIA_ShowSelState
-
- NAME
- MUIA_ShowSelState -- (V4) [I..], BOOL
-
- FUNCTION
- Normally a gadget will reverse its frame and
- display the configured MUII_SelectetBack background
- pattern in its selected state. For some objects
- (e.g. checkmarks) this is not recommended and
- can be supressed by setting MUIA_ShowSelState
- to FALSE.
-
- SEE ALSO
- MUIA_Selected
- Area.mui/MUIA_Timer
-
- NAME
- MUIA_Timer -- (V4) [..G], LONG
-
- FUNCTION
- MUIA_Timer gets triggered when a relverify button is
- pressed and (after a little delay) increases every
- INTUITICK as long as the mouse remains over the gadget.
-
- This makes it possible to have buttons repeatedly
- cause some actions, just like the arrow gadgets of
- a scrollbar.
-
- EXAMPLE
- DoMethod(btmore,MUIM_Notify,MUIA_Timer,MUIV_EveryTime,
- app,2,MUIM_Application_ReturnID,ID_MORE);
-

- Area.mui/MUIA_TopEdge
-
- NAME
- MUIA_TopEdge -- (V4) [..G], LONG
-
- FUNCTION
- You can use this to read the current position and

- up some requester below.
-
- Of course, this attribute is only valid when the
- parent window of the object is currently open.

- Area.mui/MUIA_VertWeight
-
- NAME
- MUIA_VertWeight -- (V4) [I..], LONG
-
- FUNCTION
- Adjust the vertical weight of an object. Usually
- you can simply use MUIA_Weight instead of this tag
- but in some two-dimensional groups it may become
- handy to have different horizontal and vertical
- weights.
-
- SEE ALSO
- MUIA_Weight
- Area.mui/MUIA_Weight
-
- NAME
- MUIA_Weight -- (V4) [I..], LONG
-
- FUNCTION
- This tag is a shorthand for MUIA_HorizWeight and
- MUIA_VertHeight, it sets both weights at once.
-
- The weight of an object determines how much room it
- will get during the layout process. Imagine you have
- a 100 pixel wide horizontal group with two string
- gadgets. Usually, each gadget will get half of the
- room and be 50 pixels wide. If you feel the left
- gadget is more important and should be bigger,
- you can give it a weight of 200 (and 100 for
- the right gadget). Because the left gadget is
- twice as "heavy" as the right gadget, it will
- become twice as big (about 66 pixel) as the
- right one (34 pixel).
-
- Of course giving weights only makes sense if the
- object is resizable. A MUIA_VertWeight for a
- (always fixed height) string gadget is useless.
-
- An object with a weight of 0 will always stay
- at its minimum size.
-
- By default, all objects have a weight of 100.
-
- EXAMPLE
- HGroup,
- StringGadget, MUIA_Weight, 50, End,
- StringGadget, MUIA_Weight, 100, End,
- StringGadget, MUIA_Weight, 200, End,
