DPI Aware UltraDockManager | Infragistics Forums

Hi Simon,

The issue that I have is that both the UltraButton and UltraTab controls have sized themselves to accommodate for the higher DPI.

I don't think that is the case. It's certainly not happening on my machine. I did a test just to verify. First, I updated your sample so that the "Hello" button outputs all of the sizes of the relevant controls to the Output Window. Like so:


        private void ultraButton2_Click(object sender, EventArgs e)
        {
            foreach (var dockArea in this.ultraDockManager1.DockAreas)
            {
                Debug.WriteLine(dockArea.Size, dockArea.Key);

                Debug.Indent();
                foreach (var pane in dockArea.Panes)
                {
                    Debug.WriteLine(pane.Size, pane.Key);
                }
                Debug.Unindent();
            }

            Debug.WriteLine(this.ultraButton1.Size, this.ultraButton1.Name);
            Debug.WriteLine(this.ultraButton2.Size, this.ultraButton2.Name);
            Debug.WriteLine(this.ultraTabControl1.Size, this.ultraTabControl1.Name);

        }

I then ran the sample on a machine where the FontSize/DPI was set to 100%. Then I ran the same sample on my laptop at 200%.

The results in both cases were exactly the same for every control:

100%

BottomPane: {Width=622, Height=145}
    Log: {Width=100, Height=100}
    Debug: {Width=100, Height=100}
LeftPane: {Width=195, Height=221}
    SystemExplorer: {Width=100, Height=100}
    FileExplorer: {Width=100, Height=100}
    Favourites: {Width=100, Height=100}
    CurrentWindows: {Width=100, Height=100}
RightPane: {Width=195, Height=221}
    Properties: {Width=100, Height=100}
ultraButton1: {Width=75, Height=24}
ultraButton2: {Width=75, Height=23}
ultraTabControl1: {Width=330, Height=241}

200%
BottomPane: {Width=622, Height=145}
    Log: {Width=100, Height=100}
    Debug: {Width=100, Height=100}
LeftPane: {Width=195, Height=221}
    SystemExplorer: {Width=100, Height=100}
    FileExplorer: {Width=100, Height=100}
    Favourites: {Width=100, Height=100}
    CurrentWindows: {Width=100, Height=100}
RightPane: {Width=195, Height=221}
    Properties: {Width=100, Height=100}
ultraButton1: {Width=75, Height=24}
ultraButton2: {Width=75, Height=23}
ultraTabControl1: {Width=330, Height=241}

In fact, if you look at your screen shots, there is clearly less empty space around the tab captions when you run at a higher font size. So the size of the tabs has not changed in pixels.

As for the button, I think it's probably sheer luck that that the control already has enough empty space to fit the text when it's displayed at a higher font size.

Again, DPIAware means that the application code expects the DotNet framework to keep everything the same size - to make NO adjustments for system settings font size and to leave it entirely up to the code to adjust as needed. That's the whole purpose of that setting.

You seem to want the application to adjust without you have to do anything. The DotNet framework does this by default - or least tries to. It's often not completely successful since it takes such a broad approach.
