Any way to set font for Window and its children? Topic is solved

[cd_hodges]

I was wondering if there is a way to sent a font for say a panel and have it propogate down to its children?

I'm working with a cross-platform app (Windows,Mac) and I need to be able to set basically a global font but i'd settle for the ability to set a font for a wxPanel and have its children change to that font.

thanks,

Did you took a look at the docs? wxWindow::SetFont

Something like this will probably do the trick:

Code: Select all

std::stack<wxWindow*> window_stack;
window_stack.push(parent_window);
while(!window_stack.empty())
{
    wxWindow* current = window_stack.top();
    window_stack.pop();
    current->SetFont(font);
    wxWindowList list = parent_window.GetChildren();
    for(WindowList::Node *node = list.GetFirst(); node; node = node->GetNext())
        window_stack.push(node->GetData());
}

I can't remember if wxWindowList is the correct name for what GetChildren returns but thats the essential logic.

Oh, forgot to mention that is only if you want to do it after the parent window and children have been created. If you SetFont() (like vdell said) before you create the children, they will inherit the font. Someone correct me if I'm wrong on this (I've always assumed this is what the docs where trying to say but the whole property inheritance is a bit confusing).

Yes I did look at that but it does not seem to work at all under wxMAC. here's an example of what I tried.

wPanel *mainPanel = new wxPanel(this);
wxFont ff = mainPanel->GetFont();
ff->SetPointSize(24); // something way too large -- for testing
mainPanel->SetFont(ff);

wxPanel *subPanel = new wxPanel(mainPanel,-1);
wxTextCtrl *textCtrl = new wxTextCtrl(subPanel,-1 ........


The textCtrl is not changed to use the new larger font so then I tried inserting this after the creates of each.....

subPanel->InheritAttributes();
textCtrl->InheritAttributes();

And nothing.... still doesn't take. Now I've only tested this code on the Mac - maybe its a platform thing.

So at this point I'm having to explicitly set the font for EVERY single control in my application depending on which platform I'm on.

As you can imagine this gets pretty sloppy and inefficient.

Just an idea, but have you tried to create all controls first and then call SetFont from the parent?

[cd_hodges]

Yeah I tried setting the font to the parent AFTER creating the controls but no dice. Sigh..... Looks like I'm stuck on setting the font on each individual control on the Mac platform. Sucks.
