Re: [Gambas-user] SDL component documentation
gb.sdl is incomplete ... in fact Laurent have begin to redraw all the gb.sdl lib by using OpenGl... but ... still incomplete ... i think the lack of users on this lib mess his enthusiasm (sorry for my english) Maybe if there is more user to test his work on gb3 he will purchase his work.. :/ another thing will be very fantastic in gambas ... (in my dream)... do you know Blitz Basic 3D ? try a look on it !!... it's a fabulous language that allow to easily make 3D Games. This lib just load Scene, and avatar (3D objects) and use preprogrammed actions... so in fact most of the job is done by the C lib ... i think with a tool like irrlicht engine we will be able to do a thing like Blitz... Be we are all busy and this is a job for new gambas helpers... Are we so few people to want a good Basic Language on linux ?... Is there no people so curious to create new C gambas Libs ? What are the difficulties on making gambas libs that limit the numbers of libs develloppers ? As python can do many things, Gambas can do the same and with more velocity... And a more beautifull IDE People of Gambas, Gambasians... help us to make Gambas even better, take some hour a month to add page on wiki, translate, create examples, create libs. You have idéas... it's good, you tell us to do things for you ... good ... but we are humans, with jobs, ... so like us ... you want something... try to do it yourself... and then if you can because you miss some knowlege... tell us for help ... this is the game and the philosophy of GNU world. And it's so anthousiasmic to have a piece of ourself in a great project ! NO ? Fabien Bodard This message is not only for Kevin ... :-) (Thanks kevin to try to help us !) 2009/12/2 kevinfishburne kevinfishbu...@eightvirtues.com: I've noticed that the documentation for the SDL component is incomplete. There are some basic examples in the BeastScroll example application packaged with GAMBAS, but is there a more extensive list of procedures implemented in GAMBAS for SDL? I'm guessing that the next best way of figuring out what has been implemented is to review the source code for the SDL component of GAMBAS. If that is the case, which source files should I look at to determine which SDL procedures have been implemented and how they're used? C and C++ source code is alien to me, so looking at all the files in gb.sdl/src is a bit intimidating in the context of discovering which procedures will work in GAMBAS. I consider SDL an extremely important aspect of GAMBAS, so if I could obtain the procedures and their usage/parameters I'd be willing to complete the missing documentation for them using the same syntax as the existing documentation.

Regards, Almost all of them use a Read event handler. CRFXComRX receives the most number of bytes, as it receives data from all of my temp/energy sensors. I have this defined: PUBLIC SUB RFXComRXSer_Read() DIM sData AS Byte READ #hRFXComRXSer, sData ProcessReceivedChar(sData) END So it reads data byte by byte and process them. Sure a continues flow of data, but before the latest rev. everything works with very low cpuload (with even higher serial loads) . I don't want to loose that! My guess is that now the Read event is called even when there is no data, otherwise I couldn't have a much lower load without changes to my code.

Re: [Gambas-user] Problem with tableview when in edit mode
Benoît Minisini ha scritto: Benoît Minisini ha scritto: Benoît Minisini ha scritto: When in the tableview (in edit mode) I press an arrow key, the cursor slips on every possible cell in the request direction, until it finds the end of the tableview. But this is not enough: if the cursor key is Left or Right, the cell walking goes even further, wrapping to the next or previous row and restarting. For sure there is somewhere we don't understand each other. :-) I used a few TableView in the IDE: look at the project property dialog, in the environment tab. You will see how I implemented them: the insert and delete button, the Click, Data, Insert and Save event handlers... Please tell me the difference between what I did there and what you did. When you sent me your little example, I just added a Click event handler with a call to Edit() inside, and everything worked as expected. And if things works on some computers without change, maybe they use an old version of Gambas ( 2.13). Don't take me wrong. Sometimes it seems to me that you don't read the whole message before replying, and sometimes it seems to me that the real problem is not in evidence (english language plays a role in this...). You say that you just added a Click event handler to get the program work. Well, this is not the problem. The program *is* correct (it does practically nothing). The sample program, without modifications, on some machine runs well, and on other machines shows a problem that I will explain better. When you say old version of gambas (2.13), again it seems that you didn't read carefully what I've posted. In every post I specified precisely what gambas version was installed, what os was running on, and the QT library. Now the problem. The problem is that, when the grid is in edit mode, if you press a cursor key the cursor does not move to the adiacent cell; it does not stop: it travels all the cells until it stops on the upper-left cell, or the lower-right one. By doing this, it scrolls the tableview up or down, and if the cursor key was Left or Right, it goes to the right-most or left-most, then wraps around and restarts. For every visited cell a Click event is generated. Note that in the sample program there was no Click handler, just to shows precisely that my program does nothing strange in the click handler (by doing nothing, you can't do anything strange). Now you see that I was not complaining about gotfocus, or not editable cells, or anything else. I say that a single key press should move the cursor by a single cell, not travel the whole tableview. Now the history. 1. I discovered the error on one machine, with an updated debian stable, gambas v. 2.15.2, libqt-mt.so.3.3.8, while working on an old application. Suspecting that the complexity of the application could have hide something, I wrote a new project (the sample program). Same error. Then I tried it on the other machine: same OS, same libraries, same X server - only gambas different: version 2.0.0. No error. 2. I posted a message on the list, to ask if someone else saw the same error. Two users confirmed it - one gambas 2.16, another with gambas 2.17. So the problem is alive, on at least three machines. 3. I tried on a third machine. Same os, same libraries, gambas 2.15, same remote X server. Identical situation. No error. 4. Now I am at home. Same os, same libraries, gambas 2.0.0. No error. At this point, if someone tells me that I have to modify the program to make it work, I ask myself _why_ it works (I have seen more machines on which the program works well than machines where the problem shows up). On my machines, which are four, I've seen the problem only once. But two users on this list confirmed the error. So, it seems to be an error which shows up rarely, if we want to say so. The only idea I have now is to go back to my first machine and investigate more. It is very difficult to investigate on an error if that error does not show up... Now I ask you: you say you added a Click event to make the program work properly. Why you did so? Why you say this event handler was missing? What was the wrong behaviour, when the event handler was missing? I wait for your reply; the next week I will work again on the original machine (the only one where I saw the problem), and I am determined to see over the fog.

Now you see that I was not complaining about gotfocus, or not editable cells, or anything else. I say that a single key press should move the cursor by a single cell, not travel the whole tableview. Now the history. 1. I discovered the error on one machine, with an updated debian stable, gambas v. 2.15.2, libqt-mt.so.3.3.8, while working on an old application. Suspecting that the complexity of the application could have hide something, I wrote a new project (the sample program). Same error. Then I tried it on the other machine: same OS, same libraries, same X server - only gambas different: version 2.0.0. No error. 2. I posted a message on the list, to ask if someone else saw the same error. Two users confirmed it - one gambas 2.16, another with gambas 2.17. So the problem is alive, on at least three machines. 3. I tried on a third machine. Same os, same libraries, gambas 2.15, same remote X server. Identical situation. No error. 4. Now I am at home. Same os, same libraries, gambas 2.0.0. No error. At this point, if someone tells me that I have to modify the program to make it work, I ask myself _why_ it works (I have seen more machines on which the program works well than machines where the problem shows up). On my machines, which are four, I've seen the problem only once. But two users on this list confirmed the error. So, it seems to be an error which shows up rarely, if we want to say so. The only idea I have now is to go back to my first machine and investigate more. It is very difficult to investigate on an error if that error does not show up... Now I ask you: you say you added a Click event to make the program work properly. Why you did so? Why you say this event handler was missing? What was the wrong behaviour, when the event handler was missing? I wait for your reply; the next week I will work again on the original machine (the only one where I saw the problem), and I am determined to see over the fog. Regards, No, no. I think I read you correctly. I am going to try to explain the things differently... Before Gambas 2.13, when you hit an arrow key in the TableView control, the TableView cursor was move by one cell only, and the Edit method was called automatically. So things were working *only* for TableView whose all cells are editable. For TableView having some cells read-only, the keyboard management was flawed. So, in Gambas 2.13, the Edit method is not called automatically anymore, and I decided that a cell will be considered as non-editable if the Edit method was not called during the Click event. And non-editable cells are automatically ignored when using the arrow key. That explains the behaviour you noticed in computers using Gambas = 2.13. (Let's ignore the computer #3 at the moment): for example, if you are on the top of the TableView, and if you hit the down arrow key, the current cell will be moved one by one until an editable cell is found. As you don't call the Edit method inside the Click event handler, no cell is considered as editable, and so the TableView cursor is moved down to the bottom. I hope I was clear! As for the computer #3: I don't understand that you don't have the problem, as the Gambas version is = 2.15. To fix your problem, you *have to* call the Edit() method inside the Click event handler. It will tell TableView that your cell are editable when the user use the arrow keys. But, of course, you *can* use the Edit() method outside of the Click event handler. Then things will work for Gambas =
Re: [Gambas-user] Problem with tableview when in edit mode
Benoît Minisini ha scritto: Don't take me wrong. Sometimes it seems to me that you don't read the whole message before replying, and sometimes it seems to me that the real problem is not in evidence (english language plays a role in this...). You say that you just added a Click event handler to get the program work. Well, this is not the problem. The program *is* correct (it does practically nothing). The sample program, without modifications, on some machine runs well, and on other machines shows a problem that I will explain better. When you say old version of gambas (2.13), again it seems that you didn't read carefully what I've posted. In every post I specified precisely what gambas version was installed, what os was running on, and the QT library. Now the problem. The problem is that, when the grid is in edit mode, if you press a cursor key the cursor does not move to the adiacent cell; it does not stop: it travels all the cells until it stops on the upper-left cell, or the lower-right one. By doing this, it scrolls the tableview up or down, and if the cursor key was Left or Right, it goes to the right-most or left-most, then wraps around and restarts.

Re: [Gambas-user] Directories?
2009/12/4 Dave Merriman dkmerri...@gmail.com: I've got some text files that I need to read into an array (I *really* wish Gambas had an easy way to embed array data _in_ the program, like the old data 4, 17, 32, 88... of BASIC days) It does have such a feature. It all depends on how many more ways than one you can think of to skin a cat. Take a look at the attached example.

Re: [Gambas-user] Need a Ubuntu/Linux teacher
2009/12/5 John kb2...@optonline.net: I can make a Windows box sing. I tend to agree with Emil, lots of searching and reading on google is advised, but temper it with your own knowledge - some of the stuff out there is just downright wrong. I was a Windows developer and have decades of experience with it. I learned linux and gambas by trial and error and I am still learning by trial and error to this day. This weekend alone I installed no less than six linux distros; Arch, Gentoo, Sabayon, kubuntu and Mandriva (can't remember the sixth), only to learn that I should have stayed with Ubuntu :) Ok, I learned something else too in the process. I can install qt4 on Ubuntu and have gambas create lovely qt-based apps instead of being forced to use the awful GTK engine. Yes, I could have just used kubuntu but KDE is really bloody ugly and overly complex IMO :) Anyway, that said, google, persevere and ask when you're truly stuck. There is certain je ne sais quoi about discovering for oneself what is probably common knowledge amongst the gurus. -- Join us December 9, 2009 for the Red Hat Virtual Experience, a free event focused on virtualization and cloud computing.
