Tcl/Tk:当用户更改窗口大小时如何缩放窗口小部件

Question

我有一个窗口,里面有小部件.当我手动调整窗口大小时,窗口小部件会在高度减小时自行缩放,但不会在宽度更改时或高度超出初始高度时缩放.如何使窗口小部件堆叠到窗口的边框？

用于创建窗口的代码:

wm title $base "KitKite Sparam Viewer"
set frm_main      [frame  $base.main_frm]
pack $frm_main

grid [frame $frm_main.graph ] -row 1 -column 1
set g [sparam_graph_widget $frm_main.graph graph]

grid [set frm [frame $frm_main.frm]] -row 1 -column 2
#from and to frame
set from      [frame $frm.from -relief ridge -bd 2]
set from_lbl  [label $from.lbl -text "From:"]
set f_tbl_frm [frame $from.tbl_f]
set to        [frame $frm.to -relief ridge   -bd 2]
set to_lbl    [label $to.lbl   -text "To:"]
set t_tbl_frm [frame $to.tbl_t]

grid $from      -column 1 -row 1 -sticky nwe
grid $from_lbl  -row 1 -sticky nsew
grid $f_tbl_frm -row 2 -sticky nsew
grid $to        -column 2 -row 1 -sticky nwe
grid $to_lbl    -row 1 -sticky nsew
grid $t_tbl_frm -row 2 -sticky nsew

set from_t [sparam_table_widget $f_tbl_frm f_tbl]
set to_t   [sparam_table_widget $t_tbl_frm t_tbl]

set data        [frame $frm.data]
set data_lbl    [label $data.lbl -text "Choose data type to show"]
set isi         [checkbutton $data.cb_isi -variable cb(isi) -command [list __sp_data_changed isi $g] -text ISI       ]
set xt          [checkbutton $data.cb_xt  -variable cb(xt)  -command [list __sp_data_changed xt  $g] -text XT        ]
set ref         [checkbutton $data.cb_ref -variable cb(ref) -command [list __sp_data_changed ref $g] -text Reflection]
set conf_button [button $data.bt_conf -text "Configure connections" -command [list __sp_configure_datapath]]

grid $data        -column 1 -row 2 -columnspan 2 -sticky new
grid $data_lbl    -column 1 -row 1 -columnspan 2 -sticky nsew
grid $isi         -column 1 -row 2               -sticky nsw
grid $xt          -column 1 -row 3               -sticky nsw
grid $ref         -column 1 -row 4               -sticky nsw
grid $conf_button -column 2 -row 2 -rowspan 3    -sticky nsew

grid rowconfigure $frm 1 -weight 4 -uniform 1
grid rowconfigure $frm 2 -weight 1 -uniform 1
grid rowconfigure $frm_main 1 -weight 5 -uniform 1

$base创建使用窗口的名称toplevel sparam_graph_widget和sparam_table_widget被给予他们的曲线图和表格的定制窗口小部件的框架内部的创建过程和地点(相应地)

为了使至少一个窗口小部件扩展以占用空间,您需要将至少一列设置为具有非零权重.

grid columnconfigure $containerWidget $someWidgetOrIndex -weight 1

请注意,一旦执行此操作,该列优先处理水平方向上的所有大小更改.您可以通过将多个列设置为具有非零权重来调整此值,并为不同的列提供不同的权重(-weight 2将获得两倍大的更改-weight 1).

您可能还需要调整用于pack外框的选项.通过将不同的帧设置为不同的颜色进行调试,以便您可以看到正在发生的事情......
