Each row is a QHBoxLayout, I want all of the gray space to be used up by the layout and I want the first widget to use all of the space. How can I make that happen? This is my current setup:
Layout:
layoutStretch: 1,0,0,0
layoutSizeConstraint: SetMaximumSize
The first element has the following:
sizePolicy: [Expanding, Preferred, 5, 0]
This currently behaves correctly, it's when I maximize the window that the extra space appears.
It looks like the first widget is constrained by the maximumWidth. Leave it at the default (16777215) so that it can grow as much as needed.

I have a QDockWidget with a QGroupBox as the top widget, with QVBoxLayout applied. This contains a QChartView and a QLabel.
The QLabel contains a text composed of several lines of different length.
First, I would like to have the QChartView the same width and height as the QLabel.
Second, as the content of the QLabel is updated by setText(...) in a Slot method, its content changes in height and width. So I would like to update the width and height of the QChartView above it.
For the moment, I only achieved to grow the entire DockPanel to accomodate longer and wider QLabel content, but not to shrink back when this content is narrower and less wide...
I did play with a lot of things, without real success (here a snippet of the Slot method that updates the QLabel content...):
self.fkChartView.hide()
self.pPDetailsLabel.hide()
self.pPDetailsLabel.parent().hide()
self.pPDetailsLabel.setText(self.canvas.grayScottModel.getPearsonPatternDescription(specie=type))
self.pPDetailsLabel.updateGeometry()
self.pPDetailsLabel.parent().updateGeometry()
self.pPDetailsLabel.parent().update()
self.pPDetailsDock.updateGeometry()
self.pPDetailsDock.update()
self.pPDetailsLabel.show()
self.pPDetailsLabel.parent().show()
# print(self.pPDetailsLabel.sizeHint())
self.fkChartView.setMinimumHeight(self.pPDetailsLabel.size().width())
self.fkChartView.setMaximumHeight(self.pPDetailsLabel.size().width())
self.fkChartView.setMinimumWidth(self.pPDetailsLabel.size().width())
self.fkChartView.setMaximumWidth(self.pPDetailsLabel.size().width())
self.fkChartView.updateGeometry()
self.fkChartView.show()
self.fkChartView.updateGeometry()
self.fkChartView.update()
I tried to hide the widgets, so they forget their sizes and/or sizeHint (not sure).
I tried a few updateGeometry() and update() too, but it does not seem to help.
An idea, anyone?
I had it working as intended in the end by doing this in the slot method that updates the content of the QLabel:
self.fkChartView.hide()
self.pPDetailsLabel.setText(self.canvas.grayScottModel.getPearsonPatternDescription(specie=type))
self.pPDetailsLabel.adjustSize()
self.pPDetailsLabel.parent().adjustSize()
# Sets the dimensions of the chart folowing the label width
self.fkChartView.setMinimumHeight(self.pPDetailsLabel.size().width())
self.fkChartView.setMaximumHeight(self.pPDetailsLabel.size().width())
self.fkChartView.setMinimumWidth(self.pPDetailsLabel.size().width())
self.fkChartView.setMaximumWidth(self.pPDetailsLabel.size().width())
self.fkChartView.adjustSize()
self.fkChartView.show()
self.pPDetailsDock.adjustSize()
So I first hide the QChartView, so its dimensions do not interfere,
then all the magic happens thanks to the adjustSize() call. I do this on the QLabel after its content has been updated,
then on its parent (the top QGroupBox in my QDockWidget).
The QChartView still hidden, I force its dimensions,
then show it and
finally adjust the size of the QDockWidget.
It does precisely what I want:
if text is broader, the chart expands but stays square,
if text is narrower, chart shrinks, but stays square.
Total height of the dock adjusts also to fit, without staying the longer and longer it had to be to accomodate for a big former QLabel content.
I'm trying to create an "underlay" (as opposed to overlay) widget that needs to size like the overlay widget. I can't use a Stack since it seems Stack requires its children to have a defined size. It also seems I can't use CustomMultiChildLayout since MultiChildLayoutDelegate doesn't support the container size from depending on the size of the children (per docs.)
That leaves me with MultiChildRenderObjectWidget for which I can't find a good sample anywhere.
The goal is to show a progress bar underneath a text label. The progress bar should automatically scale to the size of the text. These in turn are enclosed in a Column, and FittedBox set to scale down automatically. The FittedBox ensures the layout nicely adjusts to any screen width.
Any help hugely appreciated!
To answer my own question; CustomMultiChildLayout actually does work, and it's explained really well here.
I'm making an emacs-esque toy text editor. At startup, there's one large window (a QTextEdit derivative) in the top center of the screen, with a minibuffer (QLineEdit derivative) underneath. Both of the actual editing widgets are contained in the grids of parent classes called Window and MiniWindow (Window also keeps track of a QLabel that appears directly beneath the QTextEdit).
My Window object is at location 1, 1 in the grid, and my MiniWindow object is at 2, 1. I've set content margins to 0 and spacing to 0, which looks great at first, but when I try to grow the window by dragging on the corner, this starts to happen:
As you can see, the screen is divided into two rows (as it should be), but half of the vertical length of the screen is dedicated to each row. What I need is for the top Window to stretch its length during resizing so that it is always adjacent to the MiniWindow underneath. Is there some other option I need to be setting?
Nevermind, got it.
I was having this problem because the QLineEdit object was in the grid of my container class, MiniWindow. The height of a MiniWindow object is free to vary with the window resizing in a way that a QLineEdit alone would not be. The fix was set to the maximumHeight of MiniWindow to approximately the height of a QLineEdit, which is around 16.
Works great now.
Ok, I am beat. I tried a few things but I am unable to make this happen. I need some help now.
I want to be able to have some text and picture side by side (only one line, thus no need for wrapping or other fun. The picture is small enough to fit in a text line):
This is a text <temp.jpg placed center to the textline>
Problem is, when I use
This is a text \includegraphics{temp.jpg}
the pictures baseline is alligned with the text baseline. I want the picture (vertical) center to be aligned with the text baseline. How can I make this possible?
This is a text $\vcenter{\hbox{\includegraphics{temp.jpg}}}$
It sounds like you want \raisebox (see the raisebox section of the LaTeX wikibook), with a negative argument. Use dimensions ex (the notional height of an 'x' in the current font) or \baselineskip (the size between text baselines) as your units.
If you want to do more complicated things, such as move the graphics box down by half its height, you can, but it gets fiddly. If the graphic size isn't unpredictable, you're probably better off tuning this by hand anyway.
In my opinion, most simple answer \raisebox{-0.5\totalheight}{<your graphic here>}
This is a text \raisebox{-0.5\totalheight}{\includegraphics{temp.jpg}}
Explanation:
\raisebox moves vertically the whole text/picture given as second argument. The first argument is the vertical shift as a length. This command provides the length \totalheight which is, self-explanatory, the height of the whole text/picture that you want to raise. The factor -0.5 lowers exactly at the half of the length(as the question demands). For aesthetic adjustments just modify the factor's value.
By the way, with this method there is no need to get into math mode as in #AlexeiMalistov answer, and no need of double command \vcenter + \hbox
As far as I know ON_WM_MEASUREITEM does not get called in Custom Draw list control. It is only used if control is Owner Drawn.
I have found a way to do that, but it is somewhat a HACK and I still can not control gaps between items they are set up somehow automatically.
The trick is that you can create CImageList with the unused images of the size you need and if you assign such image list to the list control, items get resized to the dimensions close to the size of the images. After that you can use Custom Draw to paint whatever inside those enlarged items.
CImageList m_imageList1;
m_imageList1.Create(176, 144, ILC_COLOR32 | ILC_MASK, 5, 1);
GetListCtrl().SetImageList(&m_imageList1, LVSIL_NORMAL);
So the question is how do you change items size and spacing between them in Custom Drown control?
Or a fully Owner Drawn control with LVS_OWNERDRAWFIXED is my only option here?
Update.
I have compiled the same custom drawn list control in VS2008. And the look was different. The item size was perfect, and no gaps between the items. I guess that sizing problem I had was only in MFC for VS2003, I was using initially.
Man, MFC is a constant HACK spree :-)
I guess the question is closed. Thank you (me).
