News with EasyGem
|Version 4.01 from 10 September 2000
This version is different from the previous version in that some minor errors have been removed. The most significant error of the older versions was that rectangles described with parameter sets in the form (X,Y,W,H) were interpreted too small by one pixel in width and height. For example, windows and controls specified by indicating width and height were too small by one pixel.
Please use the current EasyGem version only with Omikron Basic 6.55 or later, otherwise redraw errors might occur.
|Version 4.00 from 24 July 2000
The Menu Library was completely revised and expanded with many new functions. It is now possible to manage submenus with M_Subtitle and M_End_Title. The functions M_Icon and FN M_Icon serve to assign icons to individual menu items. Starting with Mac OS 8.0, it is possible to utilize the other modifier keys for menu shortcuts as well. To this purpose, M_Modifier and FN M_Modifier were implemented. Another option available with Mac OS 8.0 as well is that the text font can be set individually for each menu item using M_Font and FN M_Font.
The option to dynamically change a menu, that is to add or remove it during runtime, is also a very important new function realized with M_Insert and M_Delete.
Another new option are pop-up menus. Three additional procedures are available for this: Def_Popup, End_Popup, and M_Show_Popup. Use these to define and display pop-up menus.
The function FN M_Handle establishes the link with the Mac OS Toolbox and thus makes it possible for experienced programmers to apply Mac OS functions to EasyGem menus.
EasyGem 4.0 may now be used to program non-modal dialog boxes. The layout for dialog boxes was optimized as well. Cell size and spaces can be modified and varied by the programmer using D_Setcellwidth, FN D_Getcellwidth, D_Setspace, and D_Getspace.
Use D_Input to create several input fields per line. Pop-up menus and dialog boxes were integrated as new object types (D_Popup). Free controls of all types can now be utilized for dialog boxes as well.
Objects can be rendered selectable or nonselectable (enabled/disabled) using D_Enable or D_Disable.
An extended command of D_Event now makes menu operations possible while a dialog box is opened (e.g., to exchange texts via the clipboard).
An action function can be assigned to each object in the dialog box with the command D_Setaction. This action function is called as soon as the user clicks on the object.
Now you can use FN D_Controlid to query the control identification number of all default objects, so that the many functions of the new Control Library can be applied to these objects as well.
The Window Library now also supports so-called float windows. These are windows that are always in the front, floating above all other windows. In order to find out, which float window is the uppermost one, the function FN Win_Floattop was implemented. The width of the info line can be changed and queried with Win_Infoheight and FN Win_Infoheight. A widening of the info line is very advantageous because that is where the user defined controls can be placed.
All EasyGem windows now feature automatically proportional window scroll bars and support smart scrolling as well (the window content follows the movements of the indicator in the scroll bar).
New bits were assigned for the Win_Flags as well, which resulted in additional setting options.
Use FN Win_Visible to determine whether an open window is also visible on screen and FN Win_Collapsed returns the information, whether a window has been folded up.
A new option is to define your own action functions with Win_Topaction, Win_Moveaction, Win_Sizeaction, and Win_Closeaction, which then can react very flexibly to actions of the users.
The Utility Library was expanded by three procedures. Get_Mouse_Local returns the mouse position in local coordinates of the uppermost window. Easy_Fnav calls the File Navigation Services (available since System 8.5), which enable a very comfortable selection of files, folders, and other objects. Event_Sent makes it possible for the EasyGem programmer to send Apple events him- or herself, for example, in order to start other programs and/or to pass files to be opened to these programs.
However, the most important part of this new version is the completely new and added Control Library. A wide range of new procedures and functions enable programmers now to define and manage free controls within dialog boxes and windows down to the last exact pixel. Almost all of the since System 8.0 newly introduced control types are supported. In addition to the already well-known objects, the Control Library may also be used to program scroll bars and sliders, progress bars, date and time icons, icons, pictures, and many more objects.
|Version 3.03 from 17 September, 1998
The Window Library was expanded with the procedure Win_Setflags and the function FN Win_Getflags. The command Set_Cursor from the Utility Library remains effective now only if your program is the active process. This prevents that the mouse cursor of the primary process can be changed by programs running in the background.
Furthermore, the Utility Library was expanded by a very powerful procedure named Display_Data, which serves the visualization of any two-dimensional data sets. The demo folder now contains the program EasyFractal.BAS, which demonstrates the use of this procedure.
