> i need to remove close,restore and minimize buttons from tk toplevel
For example,
-------------------------------------------
require 'tk'
top = TkToplevel.new{
overrideredirect true
geometry '200x150+200+200'
}
#top.withdraw.deiconify
#^^^^^^^^^^^^^^^^^^^^^^
# Sometimes, this line is required to remove the frame
# decorated by the window manager.
TkButton.new(top, :text=>'close', :command=>proc{top.destroy}).pack(:pady=>20)
TkButton.new(top, :text=>'exit', :command=>proc{exit}).pack(:pady=>20)
Tk.mainloop
-------------------------------------------
or
-------------------------------------------
require 'tk'
TkToplevel.new(:overrideredirect=>true,
:geometry=>'200x150+200+200'){|top|
TkButton.new(top, :text=>'close', :command=>proc{top.destroy}).pack(:pady=>20)
TkButton.new(top, :text=>'exit', :command=>proc{exit}).pack(:pady=>20)
}
Tk.mainloop
-------------------------------------------
However, when remove the window manager's frame,
you cannot move the toplevel window by mouse.
If you need to do that, you have to make bindings to control the toplevel.
The following is a sample of "Non-rectangle window" (Windows only).
------------------------------------------------------------------------
require 'tk'
TRANS_COLOR = '#020202' # Transparent color.
# Of course, any color is available which is
# not used at non-transparent part.
root = Tk.root.title('Non-rectangle and half-transparent window demo')
root.overrideredirect = true
root.attributes(:transparentcolor=>TRANS_COLOR) # set transparent color
x = 300
y = 200
# color = '#66bb88'
color = 'DarkSeaGreen'
root.attributes(:alpha=>0.75) # alpha setting (half-transparent setting)
# 0.0 (full trans) ~ 1.0 (non trans)
# In this script, use a canvas widget as a base frame.
# One of the other ways is a label widget with a photo-image.
c = TkCanvas.new(root, :width=>x, :height=>y,
:highlightthickness=>0,
:background=>TRANS_COLOR).pack
# draw a figure which is a frame of non-rectangle window.
ov = TkcOval.new(c, [0,0], [x,y], :outline=>color, :fill=>color)
# place buttons (Only demo use. Those have no callback function.)
TkcWindow.new(c, [200, 50], :window=>TkButton.new(:text=>'button1'))
TkcWindow.new(c, [150, 100], :window=>TkButton.new(:text=>'button2'))
TkcWindow.new(c, [100, 150], :window=>TkButton.new(:text=>'button3'))
# binding to toggle the window frame of the window manager.
# It may looks complex.
# The reason of the complexity is to control the window position
# to avoid sliding of the window when toggle the window frame.
c.bind('Double-1'){
if root.overrideredirect
# with no window frame
rx = c.winfo_rootx; ry = c.winfo_rooty
root.overrideredirect = false
root.attributes(:transparentcolor=>nil) # ??????
# root.withdraw; root.deiconify # if X Window System
/^(\d+)x(\d+)\+(-?\d+)\+(-?\d+)$/ =~ root.geometry
xpos = $3.to_i; ypos = $4.to_i
dx = c.winfo_rootx - rx; dy = c.winfo_rooty - ry
root.geometry("+#{xpos - dx}+#{ypos - dy}")
else
# with a window frame
/^(\d+)x(\d+)\+(-?\d+)\+(-?\d+)$/ =~ root.geometry
xpos = $3.to_i; ypos = $4.to_i
rx = c.winfo_rootx; ry = c.winfo_rooty
root.overrideredirect = true
root.attributes(:transparentcolor=>TRANS_COLOR) # ??????
# root.withdraw; root.deiconify # if X Window System
root.geometry("+#{rx}+#{ry}")
end
}
# bindings to drag the window
mark_px = mark_py = 0
mark_geom_x = mark_geom_y = 0
c.bind('1'){
/^(\d+)x(\d+)\+(-?\d+)\+(-?\d+)$/ =~ root.geometry
mark_geom_x = $3.to_i; mark_geom_y = $4.to_i
mark_px, mark_py = c.winfo_pointerxy
}
c.bind('B1-Motion'){
x, y = c.winfo_pointerxy
root.geometry("+#{mark_geom_x + x - mark_px}+#{mark_geom_y + y - mark_py}")
}
# start eventloop
Tk.mainloop
