Was wondering if it was possible to have a drop down widget in app maker be required. In other words, users could not click submit unless they had selected a value from a down down menu. Kind of like how validation on text boxes.
When looking at the property editor for a drop down widget I don't see anything that will allow me to set the above requirement out of the box.
Below is the property editor for a drop down, you will notice there is no validation options.
Below that is the text box property editor with the validation option expanded. I basically need the same functionality for my drop down menu.
If anyone dealt with a similar issue I would appreciate any input.
Of course you have that option.
Look under DropDown menu you will find option called allowNull, deselect that option. Also select validationDisplay check box from 'Other' menu and users will have to choose from a drop down menu always.
Below are the screen for your reference,
Dropdown menu allowNull option,
Other menu validationDisplay option,

This is a screenshot if you put a Menu on a StringField:
This is a screenshot if you put a Tooltip on a StringField:
This is a screenshot if you put a Menu and a Tooltip on a StringField:
the (i) icon from the tooltip is the button to open the menu list.
the tooltip text is not visible.
Did I miss something?
Is this a known issue?
Yes, this is a known issue. If a tooltip and a menu are provided, a combined popup should be shown including the tooltip text and the menu items. But this has not been implemented yet. Feel free to open a bug.
However, if you only have one action you could set the property hasAction to true instead of using a menu. This will bring up a clickable arrow inside the field, actually intended to follow a link or open the email client. But you could also use it for any other action as well, just implement execAction. Please note that this feature is only available for string fields so far.
StringField with hasAction=true:
I followed this great example, but when I use the arrow key to go through the customized QCompleter dropdown list item, the item does not appear in the customized line editor (it is highlighted in blue in the dropdown list). when I hit the enter button, the item will appear in the line editor highlighted in blue. then i have to hit the enter button again to let the editor take the item.
this is different from how QCompleter behaves. in QCompleter, when using the arrow key to go through the items, they will automatically appear in the editor without highlight. when hitting the enter button, the editor will take the item.
I spent a lot of time debugging, but couldn't figure out what's wrong.
I think this is a bug as described here: QTBUG-3745. There you can also find a workaround.
I am using tab navigator. And it has thee tabs "Search", "Show as text", "Show on map"
I have a address search box in Search tab. I would like to hide other two tabs if search has not happened yet. So if user hasn't searched any thing other two tabs shouldn't be visible.
Can you please tell me how can I achieve this?
Hiding tabs is a preferred way.
Second option is to disable tabs until search is done.
There are a couple ways to do this.
Use the TabNavigator's getTabAt() method which returns the Button that makes up the visual tab and set the visible property to false. It can be tricky with bindings.
The other option is to addChildAt or removeChildAt on the TabNavigaor depending on what tabs you want to show or hide.
As you mention disabling could also work. Do this by as well setting the tab's container to disabled.
I had used removeChildAt on tab navigator and works fine. But if you want to do specific actions on selected Tab then you should think about other solution because the removedChild is no longer available in tab navigator.
I'm trying to design a UI in Qt and I can't find anywhere in the designer a button which can be "droped down" like combobox. What I mean by that is that I would like to have this button with his "default" option choosen so if I like it I would have to just click on it but if I would like to choose different option I would be able to clik the little arrow on the right side of this button and then pick option suitable for me at that moment.
You're looking for a QToolButton that has a set of actions or a menu set on it. From the documentation, the QToolButton::ToolButtonPopupMode...
Describes how a menu should be popped up for tool buttons that has a menu set or contains a list of actions.
Of it's values, the two that I see most frequently are DelayedPopup:
After pressing and holding the tool button down for a certain amount of time (the timeout is style dependant, see QStyle::SH_ToolButton_PopupDelay), the menu is displayed. A typical application example is the "back" button in some web browsers's tool bars. If the user clicks it, the browser simply browses back to the previous page. If the user presses and holds the button down for a while, the tool button shows a menu containing the current history list
And MenuButtonPopup:
In this mode the tool button displays a special arrow to indicate that a menu is present. The menu is displayed when the arrow part of the button is pressed.
In my flex app I have custom tooltips on buttons that hide and show based on user context.
The problem that I dealing with is that when I call my showTips() function I only want to show tooltips on the buttons that visible in the view. So buttons that on a un-selected tab (tabNavigator) should not show the tooltips.
For some reason all tooltips are showing.
Is there a way to detect if a button is not in current view, like on a un-selected tab?
If you gave us some code I could check this out, but would this work?
if(button.parent.visible) { showTip(button);}
Instead of custom coding for each button, make use your tabnavigator's creation policy is set to "auto".
