I have created a drawer, which will appear after click and drag from top of the screen using mouse.I have also added a list view. But the problem is; when more list items are added in the list view, drawer height is not correct. Extra added list items are visible in the top of the screen even without dragging the drawer down. Is there any solution for this?

I have a QMenubar inside QMainWindow. I have set it to be displayed on the right corner using setCornerWidget. But the menu items are going out of the main window. How can I prevent the menu to be displayed within the window?
I have already tried menu->setLayoutDirection(Qt::RightToLeft) which is giving me a mirror image of the current menu display as seen below, but that does not look good to me. Is there a way to keep the direction from Qt::LeftToRight and still be able to contain the menu inside the window?
I have been having issues with using the ScrollToAsync function of a ScrollView when running on Android, not tested on iOS yet.
I'm using Xamarin.Forms version 2.5.1.444934 using .Net Standard
Testing on the Android Emulator (8.0, API26) and a Google Pixel (8.1 API27), both have the same issue.
I use NavigationPage and Navigation.PushAsync to move between pages (therefore have navigation bars on every page).
I want to create an auto populate field control, the user types in the first few letters and I look up the results in a database / static list of string and display the results below for the user to click/tap.
I have this working using a composite control (the contents of the frame marked interesting below).
The problem I have is scrolling the view to show the results.
My page has this layout hierarchy:-
ContentPage
StackLayout
ScrollView
StackLayout
Frame (some label and entry fields inside a stack layout)
Frame (some label and entry fields inside a stack layout)
Frame (some label and entry fields inside a stack layout)
Frame (the interesting one that deals with scrolling)
StackLayout
Heading Label
StackLayout
Label x:Name="ScrollToLabel"
Entry x:Name="ScrollToEntry"
Grid x:Name="ScrollToGrid"
Entry x:Name="Hidden" Text="I should stay visible as you type"
/StackLayout
/StackLayout
/Frame
Frame (some label and entry fields inside a stack layout)
Frame (some label and entry fields inside a stack layout)
/StackLayout
/ScrollView
StackLayout
Button Text = Done
/StackLayout
/StackLayout
/ContentPage
When the user clicks/taps in to ScrollToEntry, the keyboard opens and pans the control to above the keyboard (ok so far).
When the user starts typing in ScrollToEntry, the code populates ScrollToGrid with up to 5 results.
At this point I want to make sure that the grid results are visible for the user to tap on.
I have tried 2 different options, ScrollToAsync(ScrollToLabel, Start) and ScrollToAsync(Hidden, MakeVisible).
Neither work as I would like 100% of the time.
ScrollToAsync(ScrollToLabel, Start)
If the ScrollToEntry is at the bottom of the screen, the navigation bar is hidden and the view pans up too far.
The ScrollToLabel is now off the top of the screen.
When the second letter is clicked/tapped, the Navigation bar is restored and the scroll scrolls correctly, ScrollToLabel at the top of the screen.
If the ScrollToEntry is near the top of the screen, the navigation bar is not hidden and it scrolls correctly.
ScrollToAsync(Hidden, MakeVisible)
This is my preferred option because it would only scroll as far as needed to display all the results (not all the way to the top).
This works even worse than the first one.
In most cases, it does not scroll at all, I assume it thinks it already visible but is actually behind the keyboard?
If it does scroll, the label Hidden is still not displayed (I tested with both a HeightRequest="0" version and a visible version, both the same result).
I tried using the below code to change the adjust to resize.
Application.Current.On<Xamarin.Forms.PlatformConfiguration.Android>().UseWindowSoftInputModeAdjust(WindowSoftInputModeAdjust.Resize);
2 issues,
1. Because it resizes, the Done button now is above the keyboard, taking up space.
2. When clicking the hardware back button (not the done or navigation back button) the previous view now has a white space where the keyboard was.
If using the done or navigation back, the screen initially appears with the white space but then refreshes to full screen.
I have created a sample app that highlights the issues (by default using pan, not resize).
It's the most simple version of the layout I'm using...
Am I doing something wrong or is this just how it works? If its how it works, this must be a bug? If I'm doing it wrong, can someone tell me what or suggest a different way of doing it?
I have a list where every element has a share button, when I press on the
share button a box/bubble opens up with the social mdia buttons.
when the share box opens it should go over the list items (even if it covers the next elements on the list), how can I achieve that?
current state
The box shouldn't push the height of the item list it should be on top of everything
Why does the widgets inside a QTabWidget don't resize?
All my widgets resize except for the ones inside the tabs, even the tabs resize, but not the items inside it.
Is this because of the type of layout as I show in the figure?
I can's assign a layout to it. this is before and after maximizing the window.
Why can't you assign a layout to it? You just have to give each tab a layout. Drag your widget into the tab. Select the tab, not the widget, click on one of the layouts in the top row of the designer. Your widget will fill the whole tab and resize nicely.
I am using a horizontal tilelist in flex to display an image gallery with only one item in horiz. tilelist being shown at a time. I have next and previous buttons on both sides.
The problem is I want to display a particular item/image in that list when user clicks on a thumb image from another thumbimages tilelist at bottom.
I used someTilelist.selectedIndex property but it just selects that particular index in list, it does not show that particular item/image. I want the list to show that particular image, not just select it. Please take note that the horiz. tilelist shows only one image at time.
tilelist.scrollToIndex(index);
