一组有用的Tkinter小部件。
belfrywidgets的Python项目详细描述
一组有用的tkinter小部件和巨型小部件。
此软件包包含：
- 折叠窗格：
- 可通过单击标签折叠的LabelFrame派生项。
- 标签按钮：
- 标签派生，可以像按钮一样单击，具有滚动和焦点。
- 标签笔记本：
- 提供Safari样式选项卡的笔记本，带有可选的关闭按钮 按标签。
- 向导：
- 带有prev/next/finish/cancel按钮的向导对话框，该对话框将继续 通过多个窗口小部件。
- 滚动列表框：
- 带有滚动条的列表框小部件，类似于ScrolledText小部件。
- 进度条：
- 圆形进度条，功能类似于tkinter.ttk.progress bar， 除了颜色在所有平台上都更容易控制。
- 工具提示：
- 将工具提示附加到小部件，因此将鼠标悬停在该小部件上将 显示一个小的工具提示消息。
折叠窗格
示例代码：
from belfrywidgets import CollapsiblePane
tk = Tk()
cp = CollapsiblePane(
tk,
text="Click Here to Collapse",
visible=True,
collapsible=True,
)
cp.pack(side=TOP, fill=BOTH, expand=1, padx=5, pady=5)
lbl1 = Label(cp.holder, text="This is a label.")
lbl2 = Label(cp.holder, text="This is another label.")
lbl1.pack(side=TOP)
lbl2.pack(side=TOP)
tk.mainloop()
选项卡式笔记本
示例代码：
from belfrywidgets import TabbedNoteBook
def _closeit(name):
print("Close tab %s" % name)
return True # Return True to allow closing tab.
tk = Tk()
tnb = TabbedNoteBook(tk, width=640, height=480)
tnb.pack_propagate(False) # Keep noteboox from shrinking to fit contents.
tnb.pack(side=TOP, fill=BOTH, expand=1)
pane1 = tnb.add_pane(
'one', 'First Pane',
closecommand=lambda: _closeit('one')
)
lbl1 = Label(pane1, text="This is a label.")
lbl1.pack(side=TOP, fill=BOTH, expand=1)
pane2 = tnb.add_pane(
'two', 'Second Pane',
closecommand=lambda: _closeit('two')
)
lbl2 = Label(pane2, text="This is a second label.")
lbl2.pack(side=TOP, fill=BOTH, expand=1)
pane3 = tnb.add_pane(
'three', 'Third Pane',
closecommand=lambda: _closeit('three')
)
lbl3 = Label(pane3, text="This is a third label.")
lbl3.pack(side=TOP, fill=BOTH, expand=1)
lbl = tnb.pane_label('two')
lbl.config(text="Tab 2")
tk.mainloop()
向导
示例代码：
from belfrywidgets import Wizard
root = Tk()
wiz = Wizard(
width=640,
height=480,
cancelcommand=lambda: print("Cancel"),
finishcommand=lambda: print("Finish"),
)
def disable_finish():
wiz.set_finish_enabled(False)
def enable_finish():
wiz.set_finish_enabled(True)
pane1 = wiz.add_pane('one', 'First', entrycommand=disable_finish)
lbl1 = Label(pane1, text="This is the first pane.")
lbl1.pack(side=TOP, fill=BOTH, expand=1)
pane2 = wiz.add_pane( 'two', 'Second')
lbl2 = Label(pane2, text="This is the second pane.")
lbl2.pack(side=TOP, fill=BOTH, expand=1)
pane3 = wiz.add_pane(
'three', 'Third',
entrycommand=enable_finish,
prevcommand=disable_finish
)
lbl3 = Label(pane3, text="This is the third pane.")
lbl3.pack(side=TOP, fill=BOTH, expand=1)
# wiz.show_pane('two')
# wiz.del_pane('two')
# wiz.set_prev_enabled(True)
# wiz.set_next_enabled(True)
root.wm_withdraw()
root.wait_window(wiz)
滚动列表框
示例代码：
from belfrywidgets import Wizard
root = Tk()
lbox = ScrolledListbox(
root,
horiz_scroll=False,
vert_scroll=True,
width=30,
height=15,
)
lbox.pack(side=TOP, fill=BOTH, expand=1)
for i in range(1,51):
lbox.insert(END, "Item %d" % i)
tk.mainloop()
进度条
不确定模式示例代码：
from belfrywidgets import ProgressBar, INDETERMINATE
tk = Tk()
tk.config(background="#446")
pb = ProgressBar(
tk, mode=INDETERMINATE,
bordercolor="#446",
foreground="red",
background="cyan"
)
pb.pack(fill=BOTH, expand=1, padx=10, pady=10)
pb.start()
tk.after(20000, pb.stop)
tk.mainloop()
确定模式示例代码：
from belfrywidgets import ProgressBar, DETERMINATE
tk = Tk()
tk.config(background="#446")
v = DoubleVar()
v.set(0.0)
pb = ProgressBar(
tk, mode=DETERMINATE,
maximum=200,
variable=v,
bordercolor="#446",
foreground="red",
background="cyan"
)
pb.pack(fill=BOTH, expand=1, padx=10, pady=10)
def inc():
v.set(v.get()+1)
if v.get() < 200:
tk.after(100, inc)
inc()
tk.mainloop()
工具提示
示例代码：
from belfrywidgets import ToolTip tk = Tk() ent = Entry(tk) txt = Text(tk, borderwidth=2, relief="sunken") ent.pack(side=TOP, padx=5, pady=5) txt.pack(side=TOP, padx=5, pady=5) txt.insert(END, "Tagged Text\n", "footag") txt.insert(END, "Untagged Text\n") ToolTip(ent, "This is an entry widget.") ToolTip(txt, "This is a text widget.", tag="footag") tk.mainloop()
