I want to add 4 navigation button in a panel. For Go to First page , previous page, next page, last page [<< < >> >]. I want these buttons in a row but MFC automatically put them in a column. Is there a work around to achieve this.
Thanks
Did you associate these buttons with large (32x32) images? Otherwise, the MFC Ribbon is always trying to put them into the column. In addition, you've to call SetAlwaysLargeImage method for each button to prevent button size decreasing when the frame is being resized.

In my ionic 2 application, we are have a page which shows date picker on click of a button. When date picker is displayed, if app goes in background, we are displaying a lock screen modal. The problem is when we show the modal, the date picker is displaying on top of the modal. Does anyone have an idea about how to handle this?
You may probably need to adjust z-index property of the datepicker within the stylesheet (decrease the value, so it is less than the one for modal), so it will not be rendered on top of the modal.
I am programming a game and I have a tab widget which takes up the majority of the window. I want to use the extra space in the tab bar for buttons. I have the tab widget in a grid layout. To accomplish this, I use the code below in order to remove and add back the button widgets to the desired areas (the solution to someone else's question).
ui->centralLayout->removeWidget(ui->exitButton);
ui->centralLayout->removeWidget(ui->ResizeButton);
ui->centralLayout->addWidget(ui->ResizeButton,0,4, Qt::AlignTop|Qt::AlignRight);
ui->centralLayout->addWidget(ui->exitButton,0,4, Qt::AlignTop|Qt::AlignRight);
This does not work for me; however, because I would like the second widget-- the resize button-- to be just to the left of the exit button. What is occurring is that it instead overlaps the exit button. I simply need to move it 21 pixels to the left and have no idea how!
I tried putting both buttons in a frame and then removing and adding the frame the way I did the buttons. Unfortunately the same functions I used do not exist for the qt frame object.
Here are some pictures of my window.

you are using void QGridLayout::addWidget(QWidget * widget, int row, int column, Qt::Alignment alignment = 0) overload.
2-nd and 3-rd parameters are row and column of a grid. And you put 2 widgets in the same cell so they are overlaping each other.
I solved my problem. Earlier when I was trying to add them to a frame and reposition it I could not but using a widget as the container for my buttons let me place them the way I was earlier attempting to individually place the buttons.
Is it possible to add some widgets to a QTabBar? I wanted to have a QComboBox to the side of the last tab, and have it only appear when the last tab is selected.
It's possible to add child overlay widgets to any widget, so the answer is: sure!
You can hook to the tab widgets's or tab bar's signals to get notified when the last tab is selected. Then use tabRect() to get the rectangle of the last tab. Position your combo box to the right of it. It'd need to be a child of the tab bar. That's it.
It might be easier to use a QStackedWidget to get your desired results. When you are using the QStackedWidget you can have different buttons outside that reveal the different widgets. Then use some custom signal for when the last button is activated to show a combobox that appears next to the last button.
Here is the link to the QStackedWidget
I've got an app that uses several CView-derived classes (actually CScrollView) to display document data. For one particular view, I want to add a fly-out edit box to add notes. That is, you'd see a tab at the bottom of the window labeled "Page Notes", and clicking on that would bring up the edit box. Clicking the tab while the edit box is visible would reduce it back to just the tab.
I thought I could use a one-tab CTabCtrl holding an edit box and just position it so that only the tab is visible initially. Capture the tab click notification and move the entire control, with edit box, into view. Clicking the tab again would move it back down so only the tab is visible.
Hosting the CTabCtrl on the CView is fine, and I can get it positioned correctly. The problem is that if the view is scrolled, the tab control is scrolled along with it, whereas I need it to "float" over the view and not be affected by any scrolling. I can move it back into place after the scroll, but the flickering is unsightly.
Is there a straightforward way to accomplish the "floating" effect? I mainly want the tab embedded in the view for maintenance, since it's the only view class out of the several in use that needs the "Page Notes" feature.
Should I just buckle down and put the tab in the view's parent window instead? I know it won't be affected by scrolling there, but I like the idea of keeping the tab as part of the view if possible.
It sound like the tab is functioning like a button. You click the tab and a fly out edit box appears. You could use a modeless dialog.
Select the "Page Note" and the modeless dialog comes up to edit your notes allowing you to scroll your view under the dialog.
I want to have CListCtrl.EditLabel() for any column of the list. How can I implement such a feature?
This is doable but it does require a fair bit of stuffing around with mouse clicks and focus events.
In a nutshell you trap the left mouse button down message and convert it into a cell hit details (i.e a row and column index).
With these cell details you can not determine the size and location of the list view cell and also the text value that it contains.
Now create a CEdit control directly over this cell by using size and location details from the previous step and give it the text value of the cell.
The final step is to handle the focus and keyboard enter events for the CEdit so that the text details of the CEdit can be put back into the list view cell.
It does take a fair amount of coding but when done right it does work well as an alternative to a grid control.
Don't attempt with CListCtrl.
Use the MFC Grid Control. We deploy it in an off-the-shelf app with success. It offers in-place edit, checkbox, spin, etc for all cells, as well as column and row headers, auto-size, auto-expand, colors, drag-drop.
