In a previous post I showed how you could create a constructor that a layout could use but no other code could.
Seems that in oder to make this a little more generic and cross-platform you need to look for a different stack entry.
Because macOS and Windows do things differently you can get a very different stack trace on Windows that you would on the Mac.… Read the rest
At least IMHO they are not equivalent. Why not ?
Html is a design markup language. One focused on layout and presentation. A web designer might use Adobe DreamWeaver to create the specific layout and look of a web site. And never touch a line of PHP, C, Javascript, or whatever language is used to implement the functionality of the web site.… Read the rest
Very useful words to keep in the communication between any company and its customers. Its not a promise. Just a rough outline of what things you are planning to do.
Some companies use phrases like this to let their customer base know “hey this is what we think we are going to be able to deliver” without having to promise a specific quarter or date.… Read the rest
A post on the forums got me thinking that there might be a way to simply add a whole class, module etc to a project just from code copied from the forums.
So I sat and whipped up a little IDE script that takes a clipboard and will convert it to a class or module. Now there are some tricks.… Read the rest
Suppose you write a control subclass that you want people to be able to add to a window layout OR be able to create on the fly. But you want to make sure that when an instance is constructed in code it MUST have a parameterized constructor. However, in order to put an instance on a layout by drag and drop it has to have a no parameter constructor.… Read the rest
MacOS terminal is a useful tool to know for a few really handy things.
One is getting a sample of a process after some delay so you can start doing whatever it is you want to sample.
Trying to do this in Activity monitor is not possible
But at the command line you can delay the start of the sample so you have a chance to set up the sampling and then switch back to Xojo to do the task you want sampled.… Read the rest
We’ll create a sample project to demonstrate why its a bad thing to do.
Start a new desktop project.
Add a new Class that is a subclass of ”CancelButton” by dragging a CancelButton from the library to the Navigator.
Name this new class “myPushButton”
Add a property to it – enabled as boolean
Make sure the property is public
Now on Window1 add an instance of this new button subclass.… Read the rest
Back when I was still at Xojo I wrote a blog post about what type of variable am I ?
This is a follow up on that to maybe help explain things more.
The particular difficulty is arrays. They are simple and can cause deceptive an hard to find bugs BECAUSE they are so easy to use and the Xojo language appears to do what you intend (but I don’t think it is doing the wrong thing).… Read the rest
macOS supports the notion of Alternate menus. One that even once you have opened the menu you can toggle between their textual description and short cut by pressing the Option Key or another modifier like Shift or Control.
And you can even set up several so pressing Shift is one, Shift + Ctrl is another, and Option is yet another.… Read the rest

After Joe Ranieri quit* & moved to a new job I think everyone felt stressed. I know I did. It felt like so much more was expected of an ever smaller group of developers.
By Dec of that year I’d had enough of the forums and some of the general dumping on Xojo as a product.… Read the rest
