Merge lp:~donadigo/pantheon-files/filechooser-module into lp:~elementary-apps/pantheon-files/trunk

[Adam Bieńkowski]

An elementary-styled filechooser modified dialog. It will be modified only if the pantheon-files will be the default file manager. The breadcrumbs code is taken and patched from original Files.

Test it with: GTK_MODULES=pantheon-filechooser-module app-cmd,
e.g: GTK_MODULES=pantheon-filechooser-module scratch-text-editor

The "catch dialog" method is written by tintou and is available here:
https://code.launchpad.net/~tintou/pantheon-files/gtk-module

[Rico Tzschichholz (ricotz)]

Use "if (Gtk.check_version (3, 14, 0) == null) {...}"

[Rico Tzschichholz (ricotz)]

Don't touch po/* that way

[Rico Tzschichholz (ricotz)]

Follow proposed style changes according to https://code.launchpad.net/~jeremywootten/pantheon-files/split-view-preparation-code-clean/+merge/257997

It looks like the "back" button doesn't actually go back. It goes "up". Open the dialog, notice that "back" is immediately sensitive. This shouldn't be the case as there is no navigation history. This should either be made into an actual back button (as in Files) or removed since the "up" functionality is already provided in the breadcrumb.

There seems to be a Gtk.ActionBar called "extra_and_filters" above the dialog action box. Is this actionbar necessary? Can it be removed? It causes a weird white area and double border in the open file dialog.

It seems that the new folder item should be present in the Save File dialog and not the Open Folder dialog.

Back and forward buttons are sensitive with no history in the Save as dialog which causes a segfault when clicked.

We've still got a double border issue in the action area. We're duplicated each other somewhere :p It's fine in Save As, but there's a double border in the Open File and Open Folder. Might want to make sure you've got lp:egtk trunk since I have made some small adjustments for this dialog.

Are we able to affect the places sidebar at all? Specifically it shows a "desktop" folder even though one doesn't exist. Also we'd probably want to remove the "enter location" item since the pathbar widget handles that.

In the "Save As" dialog, is it possible to move the name entry down into the action-box? There's a lot of free space in the middle there and it would save us that whole vertical area.

[Danielle Foré (danrabbit)]

Just noticed that the text input version of the pathbar doesn't actually navigate there :p

[Aneurin Hall (aneurin-hall)]

will this finally bring in icon view and scaling?

[Danielle Foré (danrabbit)]

Works fantastic now. Don't really have anything to complain about that isn't a wishlist item ;D

Thank Adam! UX Approve :)

[Fabio Zaramella (fabiozaramella)]

When i start it with an option that provides a path it doesn't open that path. e.g. In Music choosing "Change music folder" it doesn't bring up the dialog with the music folder opened.

review: Needs Information

[Adam Bieńkowski (donadigo)]

Fabio Zaramella: I think it is fixed now. You can check it by testing the newest commit.

[Jeremy Wootten (jeremywootten)]

(1) On compiling the following warning was given:

"Access to static member `CustomFileChooserDialog.chooser' with an instance reference:
     dialog_new.chooser.set_current_folder dialog.get_current_folder ());"

(2) Both Scratch and Audience gave the same error message:

"[_LOG_LEVEL_FATAL 12:39:37.465513] gee_array_list_real_slice: assertion '_tmp3_ <= _tmp4_' failed"

when changing the directory with the pathbar while opening a file. Not sure whether it is due to this branch tho'.

(3) The variable MOULDES_LIBDIR is presumably a mispelling of MODULES_LIBDIR? or MODULE_LIBDIR? It occurs in diff lines 228 and 250.

(4) Is it necessary to duplicate code and filenames in the filechooser-module directory? There are now three files named LocationBar.vala two of which duplicate code. The filechooser-module/AbstractLocationBar.vala duplicates code from /libwidgets/LocationBar.vala. filechooser-module/BreadcrumbsElements.vala duplicates code from libwidgets/BreadcrumbsElements. If this can be avoided it would make maintenance easier.

(5) diff lines 379 & following are indented 8 spaces instead of 4.

(6) Try to avoid wrapping caused by too long lines by vertically aligning parameters (e.g. diff lines 106, 167,168,290,292) (some of these may have been pre-existing in the code duplicated). Elementary code style gives a hard maximum line length of 120 characters, preferably not more than 80.

(7) The deep nesting in remove_gtk_widgets should be avoided if possible. Above 4 or 5 levels becomes hard to follow and the lines become too long.

(8) Please remove the tabs in FileChooserDialog.vala - all indents should be spaces.

(9) The "Create folder" button needs a tooltip.

(10) Formatting of diff lines 897-899 looks odd.

(11) If you change directory with the pathbar then you have to click the back button twice before the directory changes back.

I note that the problem of variable filechooser dialogs is not completely solved by this branch - for example LibreOffice and Geany still show different filechoosers.

[Adam Bieńkowski (donadigo)]

Jeremy: you can look at the newest commit. I tested it a little bit and the gee_array_list_real_slice doesn't seem to appear anymore. The eleventh point still needs to be fixed.

[Danielle Foré (danrabbit)]

Regarding Geany and LibreOffice, I'm pretty sure they're both using the Gtk2 file chooser (to which list we can add Chrome and a few others). I'm not sure there's anything we can do here. They'd have to call the Gtk3 chooser.

[Jeremy Wootten (jeremywootten)]

The functionality and compile errors are now fixed - thanks.

There is more that could be done to eliminate duplicated code but I think that is best left to a separate future branch as it would conflict with other merge proposals affecting the pathbar.

The formatting is improved but there are still some issues:
1) FileChooseDialog.vala contains tabs. I advise you view your code in a text editor that displays tabs as an arrow so you can spot them easily.
2) FileChooserDialog.vala has misaligned braces in remove_gtk_widgets (), perhaps due to trying to reduce line length. I suggest that you move the bodies of the more deeply indented foreach blocks into separate functions to reduce line length and improve clarity. e.g.

 if (w1.get_name () == GTK_PATHBAR_PATH[1])
     remove_gtkpathbar1_children (w1);

3) GTK_FILTERCHOSSER_PATH is a mispelling of GTK_FILTERCHOOSER_PATH

4) There are files added to po/. These should be removed (bzr remove po/af.po etc) if they are not in trunk.

FileChooserDialog.vala now does not contain any tabs; split remove_gtk_widgets to different methods; fixed mispelling of GTK_FILTERCHOOSER_PATH; removed unneded po files

[Adam Bieńkowski (donadigo)]

Jeremy: I think the tabs should gone now. I converted the tabs to spaces from Sublime Text. I splitted remove_gtk_widgets method to 3 methods named: transform_x_container. The po files are also gone now + GTK_FILTERCHOOSER_PATH variable name is fixed.

[lp:~donadigo/pantheon-files/filechooser-module]

1839. By Adam Bieńkowski on 2015-05-30

Fixed: wrong button response id caused not showing filter menu in some cases

[Jeremy Wootten (jeremywootten)]

There are misaligned method parameters in LocationBarChooser.vala, but as these were copied from existing code it should not block this branch.

Otherwise, all is good - thanks.
