GNU Smalltalk

And it's me again... I'm currently using seaside to create a new WEB-site and I want you to show something of the configuration I use for the connection between seaside and apache, and for configuring seaside through some lines of code instead doing ... [More] it through the configuration-dialog of seaside. Apache is configured in my case as a reverse proxy and I needed some time, to figure out, how both should be configured, to let the seaside generated sites display well. (Even with the halos etc.)read more [Less]

After playing around with seaside a bit, I want you to point you to another short seaside tutorial "HOWTO: Build a simple Seaside website in 30 minutes" under http://smalltalk.cat/blog/Seaside%3A+small+tutorial. I find it an interesting short ... [More] tutorial for seaside besides the one on: http://www.swa.hpi.uni-potsdam.de/seaside/tutorial which is also available as a book. About the first one, I don't want to explain here something, because the explanations on the mentioned WEB-Site are enough (I think).read more [Less]

Today, eventually, this is a simple advertising of the GtkLauncher, but please read on. I'm new to smalltalk and therefore, I have to learn a lot. Beside the general syntax - which seems not so hard to learn - I need an overview of the ... [More] object-library which is used. The gnu-smalltalk web-site is mostly the first place to look for information and there I found a lot of helpfull small code-snipets (like the one, how to communicate with smtp server - or the one, how to semi-automate the generation of getter- and setter methods and all the nice things).read more [Less]

Today I want to show, how to use the GtkTreeView as a table. This could be the killer-app (an emergency-case address-database for our local police-station) where we end with today: read more

Hi again, after I explained yesterday the combobox, today the labels, entries, buttons and an extension to the combobox, the ComboBoxEntry will be discussed. Because the ComboBoxEntry is an enhanced ComboBox with an entry/edit-field, we will first ... [More] have a look into the GtkEntry and in this step, automatically the Label and the Button. Afterwards, we have a short introduction to the ComboBoxEntry, which is similiar to the ComboBox - maybe, a little bit easier...read more [Less]

Writing a Widget Using Cairo and GNU Smalltalk Cairo is a powerful 2-dimensional graphics library designed to support a number of modern graphics techniques including stroking, alpha blending and anti-aliasing. It supports multiple output formats ... [More] , which allows developers to use the same code to display graphics on the screen, print them to the printer or accelerate them with OpenGL. Here is a screenshot of a cairo clock : read more [Less]

After I got now through the creation of combo-boxes, I just want today explain the creation-process. Update warning: Might be updated in the future... Currently, I use 2 extensions to the GTK.GtkComboBox ... [More] instance in this example. But I currently don't know, if there should be another way or if these changes will go into the original distribution. If that will be clear one day, i might update this thread accordingly. read more [Less]

After I had some issues with the planned subject of the next guide, I switched - for an example - to glade and would like to show, how you can do RAD with glade and gnu-smalltalk. It's really easy and fast, and you won't blow up your source-code with ... [More] the complete gui-creation stuff. As an example I picked a password-generator, because I frequently have to set passwords for different user etc. in the company I work for. read more [Less]

The thing I want to show today, is enhancing the little application with a toolbar, so let's dig into this... (Most of the applications which have menus, also have a toolbar. And it is realy easy to set up.) The nice thing, all toolbar entries ... [More] should be connected to an existing callback-method in our application, which is reachable already by an menu-entry. A toolbar is only a shortcut to an entry in the menu. So, we only have to design the user-interface, no additional business-logic is needed.read more [Less]
