在gtk.SpinButton中显示前导零 [英] display leading zero in a gtk.SpinButton

问题描述

我想在旋转按钮中使用前导零，以便始终显示两位数字.

i'd like to have a leading zero in a spinbutton in order to always have two digits displayed.

adj_hour = gtk.Adjustment(int(time.strftime("%H")),0,24,1,1)
entry_hour = gtk.SpinButton()
entry_hour.set_adjustment(adj_hour)

问题在于gtk.调整项的第一个参数必须为float/int.

problem is that gtk.Adjustment's first argument has to be float/int.

我尝试过类似的事情:

adj_hour = gtk.Adjustment(float(format(int(time.strftime("%H")), '02d')),0,24,1,1)

但它不起作用.

推荐答案

连接到 output 信号.例如，调整我链接到的文档中的C代码:

Connect to the output signal of the spin button. For example, adapting the C code in the documentation I linked to:

def show_leading_zeros(spin_button):
    adjustment = spin_button.get_adjustment()
    spin_button.set_text('{:02d}'.format(int(adjustment.get_value())))
    return True

...

entry_hour.connect('output', show_leading_zeros)
