[Gambas-user] mutex applications
I have been mucking around with this for about a year now and haven't found a solution. We have a few gambas applications that are treated as pop-ups by the users. That is, they click on some type of launcher (be it a desktop item, a menu item or in our case a wbar icon) and the application starts. Then they minimize it, or go to another desktop, or any other way to hide the application window. Then they relaunch it... ... and get another instance running. However, sort of like things like Evolution, we only want to have one copy of these applications running. So we need some sort of mutex checker that ensures that they can only run one instance of the application. So far, I have found that I can use gb.desktop to detect another instance via the window title and just exit gracefully with a Another instance of xxx is running message. Blah! That doesn't really do what I want. What I want (what I really, really want) is a way to activate the window found and then exit. Any clues? regards Bruce -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

The idea should be the following: 1) Register on the D-Bus with an unique name. 2) If it works, then export a class on the D-Bus with a method that activates yourself and eventually opens a specific document. 3) If it does not works, find the application that has registered on the bus, and use its method defined in 2) to activate it, and eventually ask it to open a new document.

[Gambas-user] Gridview keypress question
Hi List, I've got a grid with several columns. If I use the arrow keys, then the grid focus moves up/down or to the next/previous column. I want to over-ride this keypress behaviour, but can't manage it. If iI even try and detect a keypress n this event, nothing happens public Sub Gridview1_Keypress() print key.code end I''ve looked at the properties and can't seem to find one which will allow me to over-ride this behaviour. Probably something dumb I'm not seeing.

To effectively capture the key.code = key.right (or equivalent of this), I just put a if gridview1.column 0 then . Not elegant, but it does what I wanted. Must be a better way.

Part of the preparation was to fetch the Mageia 2 Gambas 3 (sounds like a football score) source rpm (version 3.1.1) and install it so that I could (1) get any of the missing build requirements, and (2) test build to check the environment. The rpm rebuild was trouble-free and all have been installed. So far, so good. I have uninstalled the 3.1.1 packages and done the reconf-all, configure, make bit. This took several hours, with a two hour car journey in the middle, but from shaky memory the only advisories I got were about jit and gnome desktop not being built. When it came to installing everything I was belatedly advised that several components were missing: gb.qt4 gb.qt4.opengl gb.xml.rpc gb.xml gb.xml.rpc gb.xml.rpc gb.xml.rpc Probably as a consequence, I could not get anything to work; ide, previously built gambas projects, no menu entries, that sort of thing. So I was wondering, are there some new requirements for building the current Gambas 3 over and above those which are used to build version 3.1.1?

Two devel packages was missing: gsl-devel and qtwebkit-devel, now it should be almost complete. Let us know if something is missing. I used that page to compare with the buildrequires in the mga2 source rpm for Gambas 3.1.1. There are quite a few differences, but as I already had executed urpmi --buildrequires [...].mga2.rpm the two libraries you mention were indeed already installed. My difficulty is in building revision #4809, or rather, it builds without obvious fault and then makes a mess of the install. My latest result is an apparently faultless install (don't ask how I achieved that, I thought I was repeating a known failing method) but still no obvious evidence that Gambas 3 is really there. There is nothing in the menu, desktop shortcuts to the ide and to a few pre-compiled Gambas 3 projects produce no visible result and executing gambas3 in a console produces the strangest error message: [richard@Bathtub gambas3-sources]$ gambas3 gbr3: no project file in '/usr/bin/gambas3'. I have reached tether's end with this one. I had just decided to update from subversion again when I saw your reply. My intention was to check out a fix for a bug on xinerama screens which Benoît had committed in revision #4808. The Big Plan was to analyse the fix and see if I could derive a patch to apply to MGA2's version 3.1.1, and then submit that to the maintainer so I could go on using stock Mageia packages for Gambas (I know my brother would benefit from the fix too). So, if you have no startling insight into why the built gb.qt4 and gb.xml stuff is not installing (every time) and why the installed gambas3 is babbling on about a Gambas project file being missing, then I think I will dump this revision and try tonight's available offering.
