C4D插件：Py4D Icon Button UI Give Away

What’s it?
Below you can find the source code for a user-area that implements a button-like interface, but additionally displays an icon on the left or right side. This icon can be a simple color or a bitmap.
IconButton UA Example
Source Code
The following is the source code for the above example. You can copy&paste the IconButton class and the AddIconButton function into your source code. As of version 1.2, the code is released under the WTFPL license, so do what the fuck you want with it!

#
# Changelog:
#
# 1.1: Corrected action msg for Command() method, information like qualifiers
# and other input event information should now be correctly received in
# the Command() method.
# 1.2: Changed license to WTFPL, do what the fuck you want with it!
# 1.3: Thanks to Jet Kawa to tell me about the flickering when holding and
# dragging. As he suggested correctly, OffScreenOn() fixes this.
# 1.4: Added mouse hover feature
# 1.5: Fixed drawing algorithm to correctly update only parts of the user
# area. The x1, y1, x2, y2 only reflect the part of the user area
# that is being redrawn, not the actual dimensions of the area. Since
# these were used to caclculate width and height of the area, rendering
# issues occured when only parts of the user area were updated (eg.
# in a scroll group).
# The standard button has been renamed to "Close" and closes the dialog
# when clicked.

复制代码

The buttons act just like normal Cinema 4D buttons. If the user presses the button, you will receive a call to your GeDialog.Command() method with the button’s ID. The IconButton interface supports three different types of icons and four different display modes.

Icon types

The icon is passed as the foruth parameter to AddIconButton()

Color constant (eg. c4d.COLOR_TEXTFOCUS)
Vector color (eg. c4d.Vector(1.0, 0.66, 0.12'))
BaseBitmap instance
Display modes

The display mode is passed as the fifth argument to AddIconButton(). The default value is IconButton.M_ICONLEFT.

IconButton.M_NOICON: Display no icon at all, just the text
IconButton.M_ICONLEFT: Display the icon on the left-hand side
IconButton.M_ICONLEFT: Display the icon on the right-hand side
IconButton.M_FULL: Scale the icon to the full size of the button.

def get_some_basebitmap():
bmp = c4d.bitmaps.BaseBitmap()
bmp.InitWith('C:/Users/niklas/Desktop/foo.png')
return bmp
class Dialog(GeDialog):
def CreateLayout(self):
AddIconButton(self, 1000, "Button One", c4d.COLOR_SYNTAX_STRING)
AddIconButton(self, 1001, "Button Two", c4d.Vector(1.0, 0.66, 0.12), IconButton.M_ICONRIGHT)
AddIconButton(self, 1002, "Button Three", get_some_basebitmap(), IconButton.M_ICONRIGHT)
AddIconButton(self, 1003, "Button Four", None, IconButton.M_NOICON)
return True
def Command(self, paramid, msg):
if paramid == 1000:
print "Button One pressed."
# ...
return True

复制代码

Adjustments

You can do any adjustments to the code you like to fit your personal needs. For example, if you want the icon to be of another size, just modify the IconButton.S_ICON value either directly on the IconButton class or on an instance.
