RESULT selection - The ID of the object which triggered the action, 0 for an error, (ULONG)(-1) for the close gadget. NOTES Simple requesters with just text and buttons can be done easier with TR_EasyRequest().

SEE ALSO TR_EasyRequest() triton.library/TR_CloseProject triton.library/TR_CloseProject NAME TR_CloseProject -- Closes a project/window. SYNOPSIS TR_CloseProject(Project) A0 VOID TR_CloseProject(struct TR_Project *); FUNCTION Closes a Triton project.

SYNOPSIS TR_CloseWindowSafely(Window) A0 VOID TR_CloseWindowSafely(struct Window *); FUNCTION Closes a window which shares its IDCMP port with another window. All the pending messages (concerning this window) on the port will be removed and the window will be closed. Do *NOT* use this function to close windows which have an IDCMP port set up by Intuition. If you do the port will be left in memory! If you intend to open a lot of windows all sharing the same IDCMP port it is easiest if you create a port yourself and open all windows with newwin.IDCMPFlags set to 0 (this tells Intuition NOT to set up an IDCMP port). After opening the window set win->UserPort to your message port and call ModifyIDCMP() to set your IDCMP flags. When you then receive messages from Intuition check their imsg->IDCMPWindow field to find out what window they came from and act upon them. When closing your windows call TR_CloseWindowSafely() for all of them and delete your message port. INPUTS Window - pointer to the window to be closed. NOTE This function is for the advanced Triton user. SEE ALSO intuition.library/CloseWindow() triton.library/TR_CreateApp triton.library/TR_CreateApp NAME TR_CreateApp -- Creates a Triton application.

An application is required for opening windows and polling messages. All projects of an application will share one IDCMP port and one memory pool. TAGS TRCA_Name - (STRPTR) Unique name for the application. Must not be longer than 20 characters. Case-insensitive. ' ', '/', '.' and ':' are not allowed. TRCA_LongName - (STRPTR) A user-readable name for the application. Up to 60 characters allowed. TRCA_Info - (STRPTR) Information about the application. Should not be more than 2 lines with 60 characters each. TRCA_Version - (STRPTR) Internal version of the application. TRCA_Release - (STRPTR) Release number of the application. TRCA_Date - (STRPTR) Creation/compilation date. Should be given in standard version string format.

(V6) SYNOPSIS message = TR_CreateMsg(App) D0 A1 struct TR_Message * TR_CreateMsg(struct TR_App *); FUNCTION Creates an empty message to be filled in by a custom class which wants to send a user message. The message is automatically added to the application's message queue (which is emptied by user-level calls to TR_GetMsg()). The trm_App field of the message is initialized to the supplied app. When called within a method which is invoked by TR_GetMsg() (i.e. an event-handling method) trm_Project, trm_Seconds, trm_Micros and trm_Qualifier are also initialized.

The following list shows the window and menu tags. See the class descriptions for the object tags. TRWI_Title (STRPTR) - The window title (changeable) TRWI_ScreenTitle (STRPTR) - The screen title (changeable) (V2) TRWI_Flags (ULONG) - The Triton window flags: - TRWF_BACKDROP : Create a backdrop borderless window in full screen size - TRWF_NODRAGBAR : No dragging bar - TRWF_NODEPTHGADGET : No depth arranging gadget - TRWF_NOCLOSEGADGET : No close gadget - TRWF_NOACTIVATE : Don't activate window - TRWF_NOESCCLOSE : Don't send TRMS_CLOSEWINDOW when Esc is pressed - TRWF_NOPSCRFALLBACK : Don't fall back onto default PubScreen - TRWF_NOZIPGADGET : No zip/zoom gadget - TRWF_ZIPCENTERTOP : Center zipped window on screen title bar - TRWF_NOMINTEXTWIDTH : Window title text length doesn't count for window size calculation - TRWF_NOSIZEGADGET : No size gadget - TRWF_NOFONTFALLBACK : Don't fall back to topaz/8 - TRWF_NODELZIP : Don't zip the window when Del is pressed - TRWF_SIMPLEREFRESH : Use simple instead of smart refresh. (V1) This flag is *obsolete* in V3+! The refresh type is now set by the user. - TRWF_ZIPTOCURRENTPOS : Zip the window without changing its position. Requires OS3.0 or higher. - TRWF_APPWINDOW : Create an AppWindow even if no object reacts on dropped icons - TRWF_ACTIVATESTRGAD : Activate the first string gadget after opening the window - TRWF_HELP : When the user presses <Help> over a menu item or a display object, a TRMS_HELP message will be sent (V2) - TRWF_SYSTEMACTION : When a system action IDCMP message arrives, a corresponding Triton message will be generated. These are currently TRMS_DISKINSERTED and TRMS_DISKREMOVED. (V4) TRWI_Underscore (UBYTE *) - The underscore for menu and gadget shortcuts. The default is "_". TRWI_Position (ULONG) - The window position: - TRWP_DEFAULT : Let Triton choose a good position for the window (default; preferred) - TRWP_BELOWTITLEBAR : Left side of screen; below the title bar - TRWP_CENTERTOP : Top of screen; centered on the title bar - TRWP_TOPLEFTSCREEN : Top left corner of screen - TRWP_CENTERSCREEN : Centered on the screen - TRWP_CENTERDISPLAY : Centered on the currently displayed clip - TRWP_MOUSEPOINTER : Centered under the mouse pointer TRWI_CustomScreen (struct Screen *) - A custom screen on which the window will be opened TRWI_PubScreen (struct Screen *) - A public screen on which the window will be opened. The screen *must* have been locked. TRWI_PubScreenName (STRPTR) - A public screen on which the window will be opened. Triton will try to lock the screen with the specified name. It will fall back onto the default public screen in case the screen can't be found/locked if you don't specify TRWF_NOPSCRFALLBACK. TRWI_PropFontAttr (struct TextAttr *) - The proportional font. If Triton can't open the font or the window would become too big for the screen with this font and you didn't specify TRWF_NOFONTFALLBACK, Triton will try to use topaz/8 instead. TRWI_FixedWidthFontAttr (struct TextAttr *) - The fixed-width font. If Triton can't open the font or the window would become too big for the screen with this font and you didn't specify TRWF_NOFONTFALLBACK, Triton will try to use topaz/8 instead. TRWI_Backfill (ULONG) - The backfill type: - TRBF_WINDOWBACK : Default window background; Can be changed by the user in the Triton Preferences editor - TRBF_REQUESTERBACK : Default requester background; Can be changed by the user in the Triton Preferences editor - TRBF_NONE : No backfill (i.e. fill with BACKGROUNDPEN) - TRBF_SHINE : Fill with SHINEPEN - TRBF_SHADOW : Fill with SHADOWPEN - TRBF_FILL : Fill with FILLPEN - TRBF_SHINE_SHADOW : Fill with a pattern composed of SHINEPEN and SHADOWPEN - TRBF_SHINE_FILL : ~ SHINEPEN and FILLPEN - TRBF_SHINE_BACKGROUND : ~ SHINEPEN and BACKGROUNDPEN - TRBF_SHADOW_FILL : ~ SHADOWPEN and FILLPEN - TRBF_SHADOW_BACKGROUND : ~ SHADOWPEN and BACKGROUNDPEN - TRBF_FILL_BACKGROUND : ~ FILLPEN and BACKGROUNDPEN TRWI_ID (ULONG) - An ID for the window. Identical windows (e.g. several identical data editor windows) should share the same ID, otherwise application-wide unique IDs should be used. TRWI_Dimensions (struct TR_Dimensions *) - A window dimension structure. The user program must supply a structure on its own if it wants to use this feature. Triton will *not* allocate it. If you use a dimensions structure, Triton will copy the window dimensions into it when you close the window. If you supply a filled-in dimension structure, Triton will try to open the window with these dimensions. Supply a cleared structure if you want Triton to use the default dimensions (the position may then be specified with TRWI_Position) and fill in the structure for later use. TRWI_QuickHelp (BOOL) - When this flag is set, QuickHelp windows will pop up for those objects which have QuickHelp strings assigned to them. (changeable) (V4) TRMN_Title (STRPTR) - A menu label TRMN_Item (STRPTR) - A menu item label. You may attach a keyboard shortcut to a menu by starting the label string with the shortcut followed by the project's underscore character and then the actual label. You may also use extended menu shortcuts composed of more than one character. Extended shortcuts can be specified with an underscore at the beginning, then the shortcut, again an underscore and the label. You may specify TRMN_BARLABEL instead of a string to create a separator bar in the menu. TRMN_Sub (STRPTR) - A sub-menu item label. See TRMN_Item. TRMN_Flags (ULONG) - Flags for a menu item: - TRMF_CHECKIT : The menu item may be checked. - TRMF_CHECKED : The menu item is checked. You may, but you do not need to specify TRMF_CHECKIT in addition. - TRMF_DISABLED : The menu / (sub) item will be ghosted.
