| t1mp | nik90: hi | 10:22 |
| nik90 | t1mp, Hi, I am having an issue in my app with the latest UITK in rc-proposed where the back button disappeared in a few pages. I was able to narrow it down the reason to https://bugs.launchpad.net/ubuntu/+source/ubuntu-ui-toolkit/+bug/1565811 | 10:24 |
| ubot5` | Launchpad bug 1565811 in ubuntu-ui-toolkit (Ubuntu) "PageHeader should not have a back action if it's the first page on the stack" [High,Fix committed] | 10:24 |
| nik90 | t1mp, I have a setup similar to http://paste.ubuntu.com/15920303/ | 10:25 |
| nik90 | where I have a so called "Home Page" which I don't push into the pagestack. | 10:25 |
| nik90 | Instead I push the child pages only to the stack. As a result, when I push them, the depth is 1 | 10:25 |
| t1mp | why do you do that? | 10:26 |
| t1mp | in any case, you can set PageHeader.leadingActionBar.actions = [ Action { iconName: "back"; onTriggered: pageStack.pop(); text: "Back" } ] | 10:26 |
| nik90 | t1mp, I do that because sometimes I want to pop all child pages to return to the home page using the clear() function. | 10:27 |
| nik90 | If I had pushed the Home Page, then that would be popped from the stack as well. | 10:27 |
| nik90 | UITK Pagestack pop() function doesnt allow me to dictate how many pages I want to pop like the upstream Qt Stackview | 10:27 |
| nik90 | t1mp, And yes, at the moment I have resorted to using a custom back button. | 10:28 |
| nik90 | But that feels hacky :P | 10:28 |
| t1mp | we can only have one default behavior for the back action, either we show it or we don't show it when there is one page on the stack | 10:29 |
| t1mp | we had it documented as not showing for one page, and it worked like that with the old header, so I think the bug you pasted above was valid, and it should not show the back action | 10:29 |
| nik90 | Hmm | 10:30 |
| t1mp | I don't know the whole structure of your app, but I would say that the home page can be the first page on the stack | 10:30 |
| nik90 | fair enough | 10:30 |
| t1mp | as a side note, maybe you want to switch to the AdaptivePageLayout :) | 10:30 |
| nik90 | t1mp, it is for uNav (default navigation app on the phone) | 10:31 |
| t1mp | because it will support convergence | 10:31 |
| nik90 | so the breakage is a bit concerning and we don't yet have an idea about how we want to converge. | 10:31 |
| nik90 | we're still brainstorming about the design | 10:31 |
| t1mp | ok | 10:31 |
| t1mp | so you relied on our bug when it was not obvious that it was a bug. | 10:32 |
| nik90 | t1mp, one more question, will the SDK add default keyboard shortcuts to the back button like "Escape" ? | 10:32 |
| t1mp | if I unfix the bug to fix the app, that will break other apps again | 10:33 |
| nik90 | t1mp, yes I wasn't aware it was a bug | 10:33 |
| t1mp | right | 10:33 |
| t1mp | nik90: not that I know of, but we can ask a designer | 10:33 |
| t1mp | Femma: ^ will we have default keyboard shortcuts for a back action in a page? | 10:33 |
| nik90 | t1mp, I will give it further thought to see if I can also push the HomePage (map view) to the stack. | 10:34 |
| nik90 | but as of the moment, I know that sometimes we need to jump from stack depth 2 to the map view. | 10:34 |
| t1mp | nik90: there is keyboard navigation however so you can use TAB to select the back button and then trigger it with (I think) enter or space | 10:34 |
| nik90 | and I don't see how to do that without using the clear() function | 10:34 |
| t1mp | nik90: or multiple pop()s | 10:35 |
| t1mp | nik90: I don't know the designs for unav. Perhaps the map could be a separate layer not in the stack | 10:35 |
| t1mp | perhaps that's what you have now :) | 10:35 |
| nik90 | t1mp, that's what we have now :P | 10:35 |
| nik90 | whcih is why our child pages have depth 1 | 10:35 |
| Femma | t1mp: nik90 at the moment, the way to achieve that would be via focus. There are currently no plans to implement a back keyboard shortcut, however if there is a requirement/use case for it then we can definitely think about including it | 10:36 |
| nik90 | t1mp, see this is why you don't automate stuff in the SDK side :P .. if app devs want to hide the back button, just give them a method to do so. | 10:37 |
| t1mp | nik90: yeah. Now they can by setting leadingActionBar.actions = [] | 10:38 |
| nik90 | t1mp, yup | 10:38 |
| t1mp | nik90: maybe that is a good reason to switch to the APL :) | 10:40 |
| t1mp | nik90: it can do everything that the PageStack can do, but it has a more flexible removePage(page) function | 10:41 |
| t1mp | nik90: apl.removePages(mapPage) would do the trick for you | 10:41 |
| t1mp | nik90: https://developer.ubuntu.com/api/apps/qml/sdk-15.04.4/Ubuntu.Components.AdaptivePageLayout/#removePages-method | 10:42 |
| nik90 | t1mp, ooh that's nice..I will try to migrate to it | 10:46 |
| nik90 | thnx | 10:46 |
| t1mp | nik90: cool. Let me know if there are any issues | 10:47 |
| t1mp | or if you discover more advantages of the APL over PageStack so we can convince more people to migrate :) | 10:47 |
| nik90 | :) | 10:51 |
| t1mp | mzanetti: hello :) | 11:22 |
| mzanetti | o/ | 11:22 |
| t1mp | mzanetti: I thought it may be useful for you and nik90 to know what you both are doing for navigation, to avoid duplication of the effort | 11:22 |
| t1mp | nik90: what's up with unav? Are you planning a big redesign/rewrite? | 11:23 |
| mzanetti | yeah, I've been talking to Marcos and Nekhelesh already. As I said, I didn't really want to compete with uNav but rather just play a bit with the QML location api | 11:26 |
| mzanetti | and well, turns out its working very nicely | 11:26 |

| cariveri | Hi there. I got an error: opening shm. I read that it is a platform error. what can I do? | 14:38 |
| cariveri | it crashes HaloWord and I think some more other apps. | 14:38 |
| cariveri | my platform was ubuntu 15.04 OTA-10.1, on a bq Aquaris E5. | 14:40 |
| bzoltan_ | mhall119: it will be zsombi | 15:06 |
