Tk::HdrResizeButton - provides a resizeable button for a HList column header.
use Tk; use Tk::HList; use Tk::HdrResizeButton; my $mw = MainWindow->new(); # CREATE MY HLIST my $hlist = $mw->Scrolled('HList', -columns=>2, -header => 1 )->pack(-side => 'left', -expand => 'yes', -fill => 'both'); # CREATE COLUMN HEADER 0 my $headerstyle = $hlist->ItemStyle('window', -padx => 0, -pady => 0); my $header0 = $hlist->HdrResizeButton( -text => 'Test Name', -relief => 'flat', -pady => 0, -command => sub { print "Hello, world!\n";}, -column => 0 ); $hlist->header('create', 0, -itemtype => 'window', -widget => $header0, -style=>$headerstyle ); # CREATE COLUMN HEADER 1 my $header1 = $hlist->HdrResizeButton( -text => 'Status', -command => sub { print "Hello, world!\n";}, -column => 1 ); $hlist->header('create', 1, -itemtype => 'window', -widget => $header1, -style => $headerstyle );
The HdrResizeButton widget provides a resizeable button widget for use in an HList column header. When placed in the column header, the right edge of the widget can be selected and dragged to a new location to change the size of the HList column. When resizing the column, a column bar will also be placed over the HList indicating the eventual size of the HList column. A command can also be bound to the button to do things like sorting the column. On DoubleClicking a Column it is closed / re-opened. A Right-ButtonClick will resize the column to the fit the needs of all the column contents.
The widget takes all the options that a standard Button does. Note: For a proper operationthe following option MUST be specified during creation:
The column number that this HdrResizeButton is associated with. (It has to be provided to resize the appropriate column).
In addition, the following options may be specified:
The default command is associated with an open/close function for the selected column. The function is called with a Tk::HdrResizeButton reference for custom usage.
The background color used for the column Header during active state (Mouse over Header).
The foreground color used for the column Header during active state (Mouse over Header).
The relief used for the column Header Button during selected state (Button pressed).
The minwidth is used for the specific column (during resize), default: 30.
The closedminwidth is used for the specific column (while in "CLOSED" view), default: 10.
The resizerwidth is the resize sensor-area on the right border of the specific column, default: 1.
