gnocl::dialog new options

Just added -height, -width, -x and -y options to the gnocl::dialog widget.

gnocl::setOpts -new command

Sometimes I want to set a block of variables within procedure either as a set of defaults or as variables passed to a proc as options. Hitherto I've used a tcl proc to do this work but thought it high time to add this utility to the gnocl core. Ok, its not strictly graphics but it does make writing event handlers easier. Take the following for example:

doTagPopup -w %w -t %t -n %n -b %b -x %X -y %Y -matches OM|MANI|PADME|HUM|HRIH

The -w options can be used to create local variables. Here's a test snippet:


proc test-setOpts {args} { 
    gnocl::setOpts $args
    puts "$x $y $z"
 
    gnocl::setOpts [list j 4 k 5 l 6]
    puts "$j $k $l"
}

test-setOpts -x 1 -y 2 -z 3

In the first call the args string is parsed and values set en bloc. The leading '-' will be stripped away. In the second example, a paired list is given from which values will be set.

Getting text tag ranges

Completed code for returning a list of the ranges of a text tag within a gnocl::text widget.

widgetId tag ranges tagName

Implmenting text tag popup menus

Here's a short script to show how to get popup menus appearing for text tag objects.

#---------------
# texttag-popup.tcl
#---------------
#!/bin/sh
#\
exec tclsh "$0" "$@"

package require Gnocl

set txt [gnocl::text -wrapMode word]

gnocl::window -child $txt -setSize 0.25

#---------------
# display popup menu
#---------------
proc doTagPopup {args} {
   
    foreach {arg val} $args { set [string trimleft $arg "-"] $val }

    if {$t == "buttonPress" && $b == "3" } {
       
        # these may need runtime re-definition
        proc doHello {} {puts hello}
        proc doGoodBye {} {puts goodbye}
       
        set menu [gnocl::menu -title "menu" -tearoff 0]
        $menu add [gnocl::menuItem -text "Hello" -onClicked doHello]
        $menu add [gnocl::menuItem -text "Goodbye" -onClicked doGoodBye]
        $menu popup $x $y
       
        #proc doHello {} {}
        #proc doGoodBye {} {}       
    }
   
}


$txt tag create tag_popup -onEvent {doTagPopup -t %t -b %b -x %X -y %Y } -underline single  -foreground blue

$txt lorem

$txt tag apply {1 0} "1 20" -tags tag_popup

Another simple error fixed -gnocl::dialog

The gnocl::dialog command has been throwing out a 'message-type' warning. The cause of this has now been removed.

gnocl::dialog -messy closure fixed

The glib warnings put to the console when the dialog is closed has now been fixed.

gnocl::dialog

Made some enhancements here today.  Added the Gtk "other" option  to the range of dialog types, i.e. no icon. But more significantly, implemented automatic setting of type to "other" if the -child option set.

Hiitherto, the gnocl::dialog was simply a means of giving yes/no feedback. Now, however, it's more useful for the setting of parameters and other forms of settings.

Here's a snippet from my current coding project which requires export to Abiword format. The following proc will build a dialog for the setting of vars. The code is not complete, but shows how the gnocl::dialog enhancements are working.

#---------------
# set file export properties
#---------------
# Args
#
# Return
#---------------
proc abi:properties {} {
    global metaData
    global pageSetup
   
    set nb [gnocl::notebook]

    # file metadata
    set box(1) [gnocl::box -orientation vertical]
    foreach name [lsort [array names metaData]] {
        $box(1) add [gnocl::labelEntry \
            -labelWidthChars 15 \
            -align left \
            -text [string totitle $name] ] \
            -fill {1 1} -expand 0
    }

    # page setup
    set box(2) [gnocl::box -orientation vertical]
    foreach name [lsort [array names pageSetup]] {
        $box(2) add [gnocl::labelEntry \
            -labelWidthChars 15 \
            -align left \
            -text [string totitle $name] ] \
            -fill {1 1} -expand 0
    }

    $nb addPage $box(1) "%__MetaData"
    $nb addPage $box(2) "%__Page Setup"

    set dlg [gnocl::dialog \
            -title "Abiword Export Properties" \
            -child $nb \
            -buttons "%#No  %#Yes" \
            -onResponse {
                puts %v
                } ]
}
