Python Indicator stops updating after 3 times on Ubuntu

由 醉酒当歌 提交于 2021-02-10 18:13:59
问题 i am writing an Indicator in Python which should update every 5 minutes. Unfortunately the label is updated only 3 times, but then the label stays the same, although the thread still runs. For demonstration purpose, I replaced the data with the current time. #!/usr/bin/env python3 import signal import gi import threading gi.require_version('Gtk', '3.0') gi.require_version('AppIndicator3', '0.1') from gi.repository import Gtk, AppIndicator3, GObject import time class Indicator(): def __init__

(I'd like to check for an uptrend or downtrend) 回答1: You can try the following code (including your original, as you see): //@version=4 study("Trend", overlay=false) leftBars = input(3) rightBars = input(3) ph = pivothigh

R: Create Indicator Columns from list of conditions

问题 I have a dataframe and a number of conditions. Each condition is supposed to check whether the value in a certain column of the dataframe is within a set of valid values. This is what I tried: # create the sample dataframe age <- c(120, 45) sex <- c("x", "f") df <-data.frame(age, sex) # create the sample conditions conditions <- list( list("age", c(18:100)), list("sex", c("f", "m")) ) addIndicator <- function (df, columnName, validValues) { indicator <- vector() for (row in df[, toString

QSS独门秘籍：subcontrol

由 我们两清 提交于 2020-02-12 04:08:21
QSS是C++ Qt中的界面美化神器，其语法和CSS区别不大，但是QSS有一个独有的功能——subcontrol，这是CSS所没有的，一个widget往往由多个子部件构成，利用subcontrol可以对窗口部件的某些子部件做精细处理，从而使得界面美化达到定制最大化。 以下内容来源于http://qtdebug.com/QSS-Subcontrol.html http://qtdebug.com/index.html上有很多不错的教程 Subcontrol 的绘制位置由 subcontrol-origin、subcontrol-position, top, left 来指定，就先从这几个属性开始入手。 Subcontrol-Origin subcontrol-origin 定义在 parent widget 中绘制 subcontrol 的参考矩形，默认在 padding 的矩形中绘制。 The origin rectangle of the subcontrol within the parent element. If this property is not specified, the default is padding. subcontrol-origin 有 4 个值可选： margin border padding content 下图展示了 subcontrol
