Hello all, thank you for this nice library.
I’m writing a gtk4 image viewer and I’d like to use a template for a custom sub-widget (the custom widget is a display control bar with a menu and a few sliders).
The thing builds OK, but the first time it hits the main loop I see:
(vipsdisp:295869): Gtk-WARNING **: 10:51:51.888: Trying to snapshot GtkActionBar 0x55a38d7e0dd0 without a current allocation
The actionbar is the first child of my custom widget. The UI file is:
<?xml version="1.0" encoding="UTF-8"?>
<interface>
<template class="Conversionview" parent="GtkWidget">
<child>
<object class="GtkActionBar" id="action_bar">
<property name="revealed">false</property>
<child type="start">
<object class="GtkButton">
<property name="label">Replace</property>
<property name="action-name">win.replace</property>
</object>
</child>
</object>
</child>
</template>
</interface>
I’m calling gtk_widget_init_template()
in my _init()
but I guess that’s not enough in this case to link the actionbar into the scene graph correctly (is that right?). Do I need to do anything else?
I’ve searched the gtk4 examples and there doesn’t seem to be one that makes a composite widget with a UI file. Is this supported? I’ve tried with gtk 4.3.2 and with gtk master.
My code is here fwiw:
