Runtime Library Options

-creator

The RTL based option creator is used to instantiate the template galette with a Tk Window. The used creator window must have a -class property.

Acceptable Tk Windows are: toplevel for floating windows, and frame for embedded windows.

Standard Options

-text, -borderWidth, -relief, -width, -height, -background, -foreground, -highlightColor, -highlightBackground, -highlightThickness, -activeBackground, -activeForeground, -takeFocus: See the options manual entry for details on the standard options.

Window-specific Options

Command-Line Name: -package, Database Name: package, Database Class; -

The Tcl/Tk package for deployed by this galette.

Command-Line Name: -require, Database Name: require, Database Class; -

The »require« property isn’t used by the galette and may be abused as an external test condition, stored inside the galette.

The above scenario is, how I do use »require« within my own software. It is not likely to change in the future.

Command-Line Name: -gridsize, Database Name: gridSize, Database Class; -

»gridSize« expects a distance denoting the size of a cell. An item may occupy one or more of such cells.

»gridSize« is used in a fuzzy-like way. If the dimensions of neighboring items are small in compared to the actual item, then the actual item may share some space from its neighbors. The same applies if the actual item is small compare to the neighboring items –it does yield some space to them.

Command-Line Name: -command, Database Name: command, Database Class; -

This »command« fragment is executed when an item in the toolbar is activated. The Goolbar items may have their own independent commands, replacing the galette »command« property.

Command-Line Name: -ensure, Database Name: ensure, Database Class; -

Expression, the result of the »ensure« expression enables or disables all items inside the galette.

»ensure« is deployed by the ensure function. The »ensure« function parameter »parentWidget« is feed via »format« into the »ensure« expression. Thus valid substitution for ensure are »%s« and »%1$s«, place holders for »parentWidget«.

Command-Line Name: -undo, Database Name: undo, Database Class; -

»undo« holds a code fragment informing how an action from this particular Galette can be undone.

Command-Line Name: -show, Database Name: show, Database Class; -

Toolbar items may be visible or invisible. This setting is controlled via the »show« property. Suppose there are four items inside the toolbar named »a«, »b«, »c« and »d« in this situation all items will be initial visible –right after they were added to the toolbar, unless »show« was specified prior to the add commands.

Example 4.7. Implicit Visible Items


    # Create the toolbar without specifying
    # show makes all added items visible.

    .toolbar add command a …
    .toolbar add command b …
    .toolbar add command c …
    .toolbar add command d …

Example 4.8. Explicit Visible Items


    # Example hide d – and add variable space (~)
    .toolbar configure -show {a b ~ c}

Command-Line Name: -hidetitle, Database Name: hideTitle, Database Class; -

»-hidetitle« tells the window to unmap an integrated title bar.

For a Galette: the integrated toolbar automatically opens, when the title is hidden. See also galette command visibility.

Description

Galette (Palette): Implements a special-type toolbar. Galette features multiple lines of entries and deploys a gridwin for scrollbar management. The customization and context menu is reused from the toolbar.

Revision : 05/18/2009, Roger 1.1 06/26/2009

The extended interface from the goolbar is used. Focus-Ring and -takefocus management exported via the template interface.

ActiveForeground, ActiveBackground and Highlighting exported via template interface.

Synthetic events on visibility changes.

Window Command

A Window created through the galette command exposes various functions. Using these functions has the following general form:

object.option(?arg, arg, ...?)

PathName is the same as the window path name. Option and the args determine the exact behavior of the command. The following commands are possible for this window:

object.cget(option): Returns the current value of the configuration option given by option. Option may have any of the values accepted by the galette command.
object.configure(?option? ?=value, option=value, ...?): Query or modify the configuration options of the window. If no option is specified, returns a list describing all of the available options for pathName (see Tk_ConfigureInfo for information on the format of this list). If option is specified with no value, then the command returns a list describing the one named option (this list will be identical to the corresponding sublist of the value returned if no option is specified). If one or more option-value pairs are specified, then the command modifies the given window option(s) to have the given value(s); in this case the command returns an empty string. Option may have any of the values accepted by the galette command.
