Re: [fltk.bugs] [MOD] STR #2862: Fl_Table keyboard nav issue: can't use tab to navigate off the widget
DO NOT REPLY TO THIS MESSAGE. INSTEAD, POST ANY RESPONSES TO THE LINK BELOW. [STR Active] Link: http://www.fltk.org/str.php?L2862 Version: 1.3-current Fix Version: 1.3-current Fixed in Subversion repository. Fixed (a) and (b) in r9843. Partial changes for (c): examples/table-spreadsheet.cxx Regarding (a): by default FLTK uses Tab to navigate widgets. However, one can enable the new Fl_Table::tab_cell_nav() flag to allow Tab to navigate table cells. Regarding (c): the examples/table-spreadsheet.cxx example was modified to make use of this new feature, and the example works better/more predictably. More to come as other table examples are modified. The new Fl_Table::tab_cell_nav() method breaks ABI, so to to access it in FLTK 1.3.x, YOU MUST UNCOMMENT the FLTK_ABI_VERSION macro at the top of the FL/Enumerations.H file before rebuilding FLTK.

[STR Active] Link: http://www.fltk.org/str.php?L2862 Version: 1.3-current Fix Version: 1.3-current Looks like Fl_Table_Row needs some fixes as well to support keyboard navigation. So still todo: e) Fl_Table_Row should heed new tab_cell_nav() f) Fl_Table_Row needs a row focus box, similar to Fl_Browser, so user can toggle-select rows in MULTI select mode g) Fl_Table_Row needs to support things like SHIFT-Home, etc to extend selections, and other key combos to toggle selection, etc. Link: http://www.fltk.org/str.php?L2862 Version: 1.3-current Fix Version: 1.3-current ___ fltk-bugs mailing list fltk-bugs@easysw.com http://lists.easysw.com/mailman/listinfo/fltk-bugs

[STR Active] Link: http://www.fltk.org/str.php?L2862 Version: 1.3-current Fix Version: 1.3-current Made small change in r9844 so that Tab can navigate to/from the input field in foo_v2.cxx attached in this STR when the ABI feature is /disabled/. (It worked OK when ABI feature was enabled) This also fixes the test/table app, which previously had trouble with tab navigation. With r9844, status of issues is: (a) Done (b) Done (c) Tested: -- OK -- test/table -- OK: tab navigates to/from inputs examples/table-as-container -- OK: tab navigates table widgets -- FAILED -- examples/table-sort -- FAIL: because Fl_Table_Row (WIP) examples/table-with-keynav -- FAIL: can't nav to checkbox+Output -- NOT APPLICABLE -- examples/table-spreadsheet -- N/A: no other widgets to tab to examples/table-simple -- N/A: read only, examples/table-spreadsheet-with-keynav -- will be obsolete (d) TODO (e) TODO (f) TODO (g) TODO Link: http://www.fltk.org/str.php?L2862 Version: 1.3-current Fix Version: 1.3-current ___ fltk-bugs mailing list fltk-bugs@easysw.com http://lists.easysw.com/mailman/listinfo/fltk-bugs

DO NOT REPLY TO THIS MESSAGE. INSTEAD, POST ANY RESPONSES TO THE LINK BELOW. [STR New] Link: http://www.fltk.org/str.php?L2862 Version: 1.3-current Added a v2 of the test program to this STR to fix a few things in the trivial first version: 1) Needed to end() the table to prevent the input field from becoming a child of the table. 2) Added code to show the selection state of the cells, as this is relevant; apparently the table is using tab navigation for its cells; hitting tab shows it walks the cells from left-to-right, and when it hits the end, focus moves on to the input field. Probably like the Fl_Input_ widget, Fl_Table needs something like the tab_nav() method which controls how the table responds to tab navigation specifically. Also, an odd behavior was noticed in v2; assuming the table were had a tab_nav() method and it were disabled (so that tab navigation doesn't move to other widgets, causing the table to use it for itself): Tab navigates cells forward (OK) Shift-Tab navigates cells in reverse (OK) but also does a multi-cell selection (BAD) IMHO, the behavior should work this way: tab_nav() enabled: tab + shift-tab navigate widgets, table does not use tab for its own cell navigation. Only arrow key navigation can be used to navigate cells (dependent on the OPTION_ARROW_FOCUS setting), and SHIFT can be used for multicell selection. tab_nav() disabled: tab + shift-tab navigate /cells/ forward or reverse. (No multi-select behavior for Tab) Arrows should also work, and Shift-Arrows should do multiselect, dependent on OPTION_ARROW_FOCUS. Perhaps too, there should be an Fl_Table method (if there isn't one now) to control whether multicell selection should be allowed or not. I imagine there might be cases where an app doesn't want multi-cell selection, or might not want interactive cell selection at all via mouse or keyboard. (eg. a 'read only' interface, where only the program can select cells) Link: http://www.fltk.org/str.php?L2862 Version: 1.3-current ___ fltk-bugs mailing list fltk-bugs@easysw.com http://lists.easysw.com/mailman/listinfo/fltk-bugs
