Interface: WindowAttributes

This page documents the new window attributes introduced in version 8.1a4 of AlphaX. These attributes let you select which controls should be drawn when creating a new window with the [new] or the [openFile] commands. By passing appropriate values via the -attr option in these commands, one can now specify that a particular control be absent from the window.

Traditionally, document windows in AlphaX come equipped with a certain number of controls. In the top right corner of the contents area, one can find :

Other elements are also considered as window controls:

For each of these controls, there is a flag stating that this control should not be drawn. These flags are additive so that the new -attr option's value is the sum of all the flags corresponding to the elements you want to remove. A value of 0 corresponds to the traditional window layout. The flag values are shown in the table below:

No Toolbar(1 << 0)1
No Dirty State(1 << 1)2
No Vcs Popup(1 << 2)4
No Parse Popup(1 << 3)8
No Marks Popup(1 << 4)16
No Split Handle(1 << 5)32
No Message Bar(1 << 6)64
No Vertical Scrollbar(1 << 7)128
No Horizontal Scrollbar(1 << 8)256
No Close Button(1 << 9)512
No Collapse Button(1 << 10)1024
No Zoom Button(1 << 11)2048
No Resize Handle(1 << 12)4096
No Toolbar Button(1 << 13)8192

Note that in the case of the close button, the collapse button and the zoom button, specifying the corresponding flag means in fact that they will be drawn in disabled state.


Important Temporary Note

The examples below apply to the [new] and [openFile] core commands. Some modifications will be necessary in the AlphaTcl library to make them available with the redefined [new] command and with the [edit] command which is built on top of the [openFile] command. Since AlphaTcl renames the core [new] command as [__new] (with two underscores), you can try the examples directly with [__new].

Create a window without a toolbar

     new -n FooWin -attr 1

Create a window without the VCS, Parse and Marks popup controls

     new -n FooWin -attr 28

The value 28 is the sum of 16 (noMarksPopup), 8 (noParsePopup) and 4 (noVcsPopup). The vertical scrollbar's top is moved up accordingly.

Add 2 to the previous example and there will be no Dirty State button either:

 	new -n FooWin -attr 30

Create a non resizable window:

     new -n FooWin -attr 6144

because 6144 = 2048 + 4096 = noZoom + noResize

The sum of all the attributes is 8191 (since 1+2^1+...+2^12 = 2^13 - 1 = 8191). This creates a completely bare window:

 	new -n FooWin -attr 8191

The same -attr option is also supported by the [openFile] command. For instance:

     openFile -attr 6144 /Applications/AlphaX/Help/Readme
