So the topic of the day is EggStateMachine. This is a handy class for managing various states in your UI that might have complex transitions. One example might be the GNOME 3 style search pattern. The search pattern has a few states. Inital state which contains the content overview The active search state, including type-ahead … Continue reading EggStateMachine
Here is a nifty trick I’ve had up my sleeve since the Gtk 2.x days (wow, over half a decade ago!). I’ve used this on a bunch of projects over the years, and it always gets a few smiles. It has a very similar API to the early days of Clutter, where it’s inpsiration came … Continue reading EggAnimation
A common pattern you see across software targeting a recent Gtk+ stack requires the use of GtkPopover. Choosing the right default-size for that popover is an exercise in futility. Really, what you want is for the popover to shrink and grow in size based on the child, but only up to a certain point. EggScrolledWindow … Continue reading EggScrolledWindow
Today we’ll cover a playful widget. You probably won’t find many great uses for this widget, but then again, maybe you will. You can use this widget to “hide” things on the top, left, right, or bottom of a widget. The contents will slide in based on the EggSlider:position property. If someone manages to tie … Continue reading EggSlider
GSettings is awesome, no doubt about it. Another uncommon thing we need in Builder are “layered settings”. We may have user “global settings” which are different than configured “project settings”. In comes in the form of a wonderfully named EggSettingsSandwich. It let’s you stack GSettings atop one another, and read from the highest priority layer … Continue reading EggSettingsSandwich
Using object bindings with GSettings is generally a snap. However, there are few places where it breaks down. One in particular for us in Builder was with “Flags Types”. A flags type can be thought of as an integer where a bit is either on or off, indicating a feature. You can think of them … Continue reading EggSettingsFlagAction
Have you ever had to deal with lots of GBinding or signal connection (and therefore disconnections) on indirect objects? A classic example for this is the GtkTextView:buffer GObject property. It’s not uncommon to find vastly broken code when it comes to this. People will g_signal_connect() and never disconnect. Slightly better is to use g_signal_connect_object()[1]. However … Continue reading EggSignalGroup and EggBindingGroup
One of the long missed features of GtkUIManager (at least from a complex application perspective) is menu merging. This is something that gets heavily used in “plug-in oriented” software. And as you might expect, a large code-base will often migrate into this direction simply out of code hygiene. I implemented something akin to this in … Continue reading GMenu Merging
Did you know that Builder has a build panel finally? That’s right, you can actually do what the name says now. Of course, we only have one IdeBuildSystem implementation at the moment (autotools), but if you implement that interface, you too can have your project building. Note that you can write build system implementations in … Continue reading Build Panel
One of the things necessary in an IDE is the ability to create projects from templates. This is something we’ve been lacking since the beginning, and I’m finally in a position to follow through on it. So, templates. What is a template? We have a couple layers of templates needed. We have, at a macro … Continue reading Template-GLib
