Author	SHA1	Message	Date
Matthias Clasen	d17f224e71	Add search support Add a filter to GtkListBase, and move the selection to the first matching item whenever the filter changes. This is meant to be used with single selection and a string filter that is hooked up to a search entry.	2020-05-30 22:27:54 -04:00
Matthias Clasen	b73be6e344	printdialog: Port to column view This is not 100% complete. The search is not there yet.	2020-05-30 22:27:54 -04:00
Matthias Clasen	4a80f23213	printer: Fix the default value of icon-name Just set this to "printer", so we don't have to fix it up in the print dialog.	2020-05-30 20:01:14 -04:00
Matthias Clasen	3b8888acda	printbackend: Add a list model getter Now that we have a list model for printers, we can start using it.	2020-05-30 20:01:14 -04:00
Matthias Clasen	786c95e503	printbackend: Use a list store	2020-05-30 20:01:14 -04:00
Matthias Clasen	7007c72fc5	inspector: Expand the actions list	2020-05-30 20:01:14 -04:00
Matthias Clasen	9eaeb81433	inspector: Expand the resource list This is an experiment with adding a filler column.	2020-05-30 20:01:14 -04:00
Matthias Clasen	3bddbcdd52	inspector: Expand the property list It looks better this way.	2020-05-30 20:01:14 -04:00
Matthias Clasen	13d5d60db0	inspector: Expand the object tree This is how it used to look, and it looks better that way.	2020-05-30 20:01:14 -04:00
Matthias Clasen	1b24528b9c	columnview: Take expand into account When allocating columns, distribute extra space to columns that have expand set to TRUE.	2020-05-30 20:01:14 -04:00
Matthias Clasen	6e7ebc49eb	columnviewcolumn: Add an expand property This will be used to determine how to distribute available extra space in a column view.	2020-05-30 20:01:14 -04:00
Matthias Clasen	bdc6770bd9	gtk-demo: Add more scrolling benchmarks Add a listview and gridview to the scrolling benchmarks.	2020-05-30 20:01:14 -04:00
Matthias Clasen	8d2fef1e23	gtk-demo: Make gridview demo use rubberbanding	2020-05-30 20:01:14 -04:00
Matthias Clasen	90668f7e01	Add rubberband api Add an enable-rubberband property to GtkListView, GtkGridView and GtkColumnView.	2020-05-30 20:01:14 -04:00
Matthias Clasen	74f72a146c	listbase: Add rubberband selection Implement the typical rubberband selection, including autoscroll. This is only useful with multiselection, and not very compatible with single-click-activate. Therefore, it is not enabled by default, and needs to be turned on with the enable-rubber-band property.	2020-05-30 20:01:14 -04:00
Matthias Clasen	5553bf1c39	Add GtkMultiSelection This is implemented using a private GtkSet helper.	2020-05-30 20:01:14 -04:00
Matthias Clasen	77a3f81971	Add a selection model test The test shows that we are failing to emit ::selection-changed in some circumstances.	2020-05-30 20:01:14 -04:00
Matthias Clasen	b3e0353e6b	testcolumnview: Reordering in the column editor Use Ctrl-Up/Down to move the column around.	2020-05-30 20:01:14 -04:00
Matthias Clasen	780915e318	testcolumnview: Flesh out column editor Turn the column list into an editor with controls for visibility, resizability, reorderability and width.	2020-05-30 20:01:14 -04:00
Matthias Clasen	7242b801ff	columnviewtitle: Display a context menu When the ::header-menu property is set on the column, use the menu model to create and show a context menu.	2020-05-30 20:01:14 -04:00
Matthias Clasen	88669080c4	columnviewcolumn: Add a menu property Add a ::header-menu property that will be used to create a context menu for the header of the column.	2020-05-30 20:01:14 -04:00
Matthias Clasen	51e8dc924b	columnview: Add autoscroll Autoscroll when the pointer gets close to the edge during column resizing or reordering. This is similar to what the treeview does, but it is implemented using a tick callback, and has variable speed.	2020-05-30 20:01:14 -04:00
Matthias Clasen	29b5d3ab38	columnview: Allow to cancel reorder with Escape The treeview does this too.	2020-05-30 20:01:14 -04:00
Matthias Clasen	bb06fffab1	columnview: Interactive column reordering Allow rearranging columns by dragging, in the same way the treeview does. We add the "dnd" style class to the header while it is dragged, and we move the header of the dragged column to the end of its parents children, so that it gets drawn on top.	2020-05-30 20:01:14 -04:00
Matthias Clasen	94c5b00231	columnviewcolumn: Add a reorderable property This will be used for interactive column reordering in the future.	2020-05-30 20:01:14 -04:00
Matthias Clasen	59e49dafd7	columnviewlayout: Use header allocation for titles Normally, this will be identical to the column allocation, but we will temporarily change it during column reordering.	2020-05-30 20:01:14 -04:00
Matthias Clasen	d5ce5b53d6	columnviewcolumn: Add reordering helpers Add helper functions that let us temporarily give a different allocation to headers. These will be used to implement interactive column reordering in GtkColumnView.	2020-05-30 20:01:14 -04:00
Matthias Clasen	915bdf24a7	columnviewtitle: Invert on release This is necessary to make drag-to-reorder work without triggering inversion.	2020-05-30 20:01:14 -04:00
Matthias Clasen	114054266b	columnview: Interactive column resizing This copies just enough of the treeview code to get columns moving.	2020-05-30 20:01:14 -04:00
Matthias Clasen	dcea6d6cda	columnviewcolumn: Add a helper We need to check whether clicks are in the headers of columns, so let the column view get at the the header widget.	2020-05-30 20:01:14 -04:00
Matthias Clasen	a118267ab7	columnviewcolumn: Add a resizable property This will be used for interactive column resizing in the future.	2020-05-30 20:01:14 -04:00
Matthias Clasen	cc63c581c3	columnview: Add a helper The column code needs to get access to the listitem widgets that are children of the listview, so add a getter.	2020-05-30 20:01:14 -04:00
Matthias Clasen	dbc1a8ba11	columnview: Add column reordering Add an API to allow reordering columns.	2020-05-30 20:01:14 -04:00
Matthias Clasen	515a86645a	columnview: Implement horizontal scrolling The listview inside always thinks it gets its full size, and updates its horizontal adjustment accordingly. So keep our own adjustment, and update it in size_allocate.	2020-05-30 20:01:14 -04:00
Matthias Clasen	cbabb85e6d	columnview: Revise scroll-minimum handling Tweak the behavior slightly. We don't show a scrollbar as long as we have at least min-size available, but we still give the entire size to the child, up to nat-size. This matches how viewports handle scroll-minimum.	2020-05-30 20:01:14 -04:00
Matthias Clasen	1031625bd4	columnviewcolumn: Add a visible property This lets us hide columns, which is useful.	2020-05-30 20:01:14 -04:00
Matthias Clasen	65ed3aa1d9	inspector: Touch up list styling This is just the minimal amount of work to make headers recognizable.	2020-05-30 20:01:14 -04:00
Matthias Clasen	ed04c46078	inspector: Use a column view for actions A straight conversion from list box to column view.	2020-05-30 20:01:14 -04:00
