Hi everybody, I have a library implementing some protocol. That library is multithread and is responsible to delivery messages to remote nodes and retrieve it's responses. I need to visualise the whole mess running.
To do this I wrote a simple application in Java/Swing where for each remote node one thread is created. The thread will send a message and wait for response in a closed loop. Each thread is represented at GUI by a label on the screen. When it's idle the background of that label becomes green, when is waiting for response it is yellow and if timeouts it becomes red. All labels have the same information so that they have exactly the same size. Beside the request/repsonse there is events that can arrive from the nodes too. That events need to be replied as the messages. When an event arrives it's showed up on screen as a new label. When it's reply is acknowledge it's removed from the screen. In pratice there is a big container where the labels came and go and change its background colors based on messages, replies and events comming and going. I've been using FlowLayout as the "big container". The labels are added and arrange horizontally by FlowLayout. When no room is avaible at the current row, a new row is added. When the rows exceed the window size a scrowbar appears. I'm looking for something silimar with GTK2 (I'll run in a embeeded system that doesn't have GTK3). My questions are: 1) Is there some container with equivalent behavior to the Swing's FlowLayout? If no I think I'll need to build one from hbox+vbox, what would be the best aproach to it. 2) How is the best way to change the background of a label? 3) What is the better aproach when adding instantiating, adding, showing, hiding removing and freeing widgets at runtime? What can get wrong? References: https://docs.oracle.com/javase/tutorial/uiswing/layout/visual.html#flow Best regards, -- "Do or do not.
