Body
I have a very simple GUI which interacts with postgresql database. The mainframe is split into 4 quadrants with each quadrant having 4 Entry Widgets. Here is an example code of one quadrant <pre><code>my $f_blue = $bottom_half->Frame(-bg=>'BLUE')-> pack(-side=>'left', -expand=>1, -fill=>'both'); $f_blue->Label(-text=>'BLUE', -bg=>'blue', -fg=>'white')->pack(-side=>'top'); my $blue_table = $f_blue->Table(-rows => 3, -columns => 3, -fixedrows => 1, -fixedcolumns => 1, -scrollbars => 'oo', -relief => 'raised') -> pack(-side => 'top', -expand => 1, -fill=>'both'); $blue_table -> put(1,1, $blue_table->Label(-text => 'Cs-137:')); my $t_blue_cs137 = $blue_table->Entry(-selectbackground=>"blueviolet"); $blue_table -> put(1,2,$t_blue_cs137); $blue_table -> put(1,3, $blue_table->Label(-text => 'MBq')); $blue_table -> put(2,1, $blue_table->Label(-text => 'Tc-99m:')); my $t_blue_tc99m = $blue_table->Entry(-selectbackground=>"blueviolet"); $blue_table -> put(2,2,$t_blue_tc99m); $blue_table -> put(2,3, $blue_table->Label(-text => 'MBq:')); $blue_table -> put(3,1, $blue_table->Label(-text => 'Tl-201:')); my $t_blue_tl201 = $blue_table->Entry(-selectbackground=>"blueviolet"); $blue_table -> put(3,2,$t_blue_tl201); $blue_table -> put(3,3, $blue_table->Label(-text => 'MBq:')); </code></pre> When entering data using the GUI I am unable to tab to skip to the next entry. Is there a way of setting key bindings so I can loop to set <pre><code>`$t_blue_cs137` to be active PRESS TAB `$t_blue_tc99m` NOW ACTIVE PRESS TAB `$t_blue_tl201` NOW ACTIVE PRESS TAB Do the same with the next quadrant `$t_red_cs137` in frame $f_red NOW ACTIVE </code></pre> Is there a way to do this in perlTK I have tried the following <pre><code>$f_blue->bindtags( [ ($f_blue->bindtags)[$t_blue_cs137,$t_blue_tc99m,$t_blue_tl201] ] ); # fix the bindtags order so that widget events are # processed before class events $f_blue->bind("<Tab>", sub { $f_blue->focusNext; Tk->break; }); </code></pre> However, this only lets me tab between each subframe and the buttons in the GUI

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
