Python : Get gtk.treeview selection from another widget

阅读更多关于 Python : Get gtk.treeview selection from another widget

问题 It looks like the only way to get the selected item of a gtk.TreeView() is to actually click on it : tree_selection = self.treeview.get_selection() tree_selection.connect('changed', self.my_callback) self.treeview.connect('row-activated', self.my_other_callback) But what if I'm listing files in my treeview, and need a "file properties" menu item? Or a play button, that needs to access selected file to pass the filename to a player class / method ? Bonus question : How to call my_other

Asynchronously updating PyGTK tray icon

阅读更多关于 Asynchronously updating PyGTK tray icon

问题 As explained here, I have a simple tray icon using PyGTK. Being very new to GTK, it appears to me that gtk.main() is synchronous, blocking any further processing until the respective UI is closed. So how can I periodically (e.g. every 5 seconds) update/refresh StatusIcon 's icon - do I have to resort to Twisted et al. for this? 回答1: You can use gobject.timeout_add() to add periodical tasks. The first parameter is the interval in seconds, the second parameter is the callback you want to be

postgresql pgagent 的安装及使用

阅读更多关于 postgresql pgagent 的安装及使用

pgagent 作为postgresql的一个任务调度代理，在postgresql 9.0 以前是附带在pgadmin 包下面的，只是默认不安装，9.0之后作为了一个单独是的安装包。所以要使用 pgagent 定时任务调度的话还得单独安装。在安装pgagent之前还需要安装另外的2个依赖包， cmake 以及 wxGTK . 这里我选择的软件版本分别是 postgresql 9.5.1 pgagent-3.4.0下载地址：https://www.pgadmin.org/download/pgagent.php cmake-2.8.5 下载地址：http://cmake.org/download/ wxGTK-2.8.12 下载地址：http://www.wxwidgets.org/downloads/ 一、postgresql 的安装（略）二、cmake的安装将安装包上传至服务器并解压，解压后进入解压后生成的cmake-2.8.5目录，执行以下命令。 [root@lsrac97 ~]# tar zxvf pgagent-3.4.0.tar.gz [root@lsrac97 ~]# cd cmake-2.8.5 [root@lsrac97 cmake-2.8.5]# ./bootstrap && make && make install 三、wxGTK-2.8.12 的安装

Cairo context and persistence?

阅读更多关于 Cairo context and persistence?

问题 I am just getting started using pycairo, and I ran into the following interesting error. The program I write creates a simple gtk window, draws a rectangle on it, and then has a callback to draw a random line on any kind of keyboard input. However, it seems that with each keyboard input, I have to create a new context, or I get an error at the moment the program receives first keyboard input (specifically, on the .stroke() line). Error is as follows, if it matters. 'BadDrawable (invalid
